ABSTRACT
Since 2014, NASA’s K2 mission has observed large portions of the ecliptic plane in search of transitingplanets and has detected hundreds of planet candidates. With observations planned until at least early2018, K2 will continue to identify more planet candidates. We present here 275 planet candidatesobserved during Campaigns 0-10 of the K2 mission that are orbiting stars brighter than 13 mag(in Kepler band) and for which we have obtained high-resolution spectra (R = 44, 000). Thesecandidates are analyzed using the vespa package (Morton 2012, 2015b) in order to calculate theirfalse-positive probabilities (FPP). We find that 149 candidates are validated with an FPP lower than0.1%, 39 of which were previously only candidates and 56 of which were previously undetected. Theprocesses of data reduction, candidate identification, and statistical validation are described, and thedemographics of the candidates and newly validated planets are explored. We show tentative evidenceof a gap in the planet radius distribution of our candidate sample. Comparing our sample to the Keplercandidate sample investigated by Fulton et al. (2017), we conclude that more planets are requiredto quantitatively confirm the gap with K2 candidates or validated planets. This work, in additionto increasing the population of validated K2 planets by nearly 50% and providing new targets forfollow-up observations, will also serve as a framework for validating candidates from upcoming K2campaigns and the Transiting Exoplanet Survey Satellite, expected to launch in 2018.Keywords: methods: data analysis, planets and satellites: detection, techniques: photometric

1. INTRODUCTION
The field of exoplanets is relatively young comparedto most other disciplines of astronomy: the announce-ment of the first exoplanet orbiting a star similar to ourown was made only in 199526 (Mayor & Queloz 1995).Since then, the field has expanded rapidly, with severalthousand exoplanets having now been discovered. Withmany upcoming extremely large telescopes, the numberof known exoplanets and our understanding of them willonly increase.
One of the most important moments in the history ofexoplanet science was the beginning of the Kepler mission(Borucki et al. 2008). Launched in 2009, the Kepler spacetelescope observed over 100,000 stars in a single patch ofsky for four years in order to look for transits. Kepler hasbeen an overwhelming success. According to the NASAExoplanet Archive27 (accessed 2018 February 14), it is

currently responsible for 2341 verified exoplanets, morethan every other exoplanet survey combined.
Unfortunately, in 2013 the second of four reactionwheels on the Kepler spacecraft failed, preventing thespacecraft from looking at its designated field and bring-ing an end to the original mission. Fortunately, a follow-up mission, called K2, was developed that used thespacecraft’s thrusters as a makeshift third reaction wheel(Howell et al. 2014). Unlike the original Kepler mission,the K2 mission must observe new fields roughly every83 days28. As a result, K2 observations are divided into“campaigns” each corresponding to a field.
With every new campaign, K2 observes more brightstars and finds more planets orbiting these stars, sothere are new bright targets available for follow-up suchas radial velocity measurements or transmission spec-troscopy. K2 has led to the discovery of numerous can-didate and confirmed planets (Crossfield et al. 2015;Foreman-Mackey et al. 2015; Montet et al. 2015; Vander-burg et al. 2015b, 2016a; Adams et al. 2016; Barros et al.2016; Crossfield et al. 2016; Schlieder et al. 2016; Sinukoffet al. 2016; Pope et al. 2016; Dressing et al. 2017b; Hiranoet al. 2017; Martinez et al. 2017), as well as to the identi-fication of planets orbiting rare types of stars, includingparticularly bright nearby dwarf stars (Petigura et al.2015; Vanderburg et al. 2016b; Christiansen et al. 2017;Crossfield et al. 2017; Niraula et al. 2017; Rodriguezet al. 2017b,a), young, pre-main-sequence stars (Mannet al. 2016; David et al. 2016), and disintegrating plane-tary material transiting a white dwarf (Vanderburg et al.2015a).
Here, we take advantage of the large number of brightstars observed by K2 and present the identification andfollow-up of a sample of 275 exoplanet candidates or-biting stars (brighter than 13 mag) in the Kepler band-pass identified from K2 Campaigns 0 through 10. Sincethe beginning of the K2 mission, we have also obtainedspectra for all of our candidates, as well as many high-resolution imaging observations, in order to measure thecandidate host stars’ parameters and identify nearbystars (both types of follow-up aid in identification andruling out of false-positive scenarios). We also attempt tovalidate29 our candidates with vespa, a statistical valida-
28 Roughly 75 of those days are devoted to science.29 The difference between an exoplanet candidate and a val-
idated exoplanet is very important. During the original Keplermission, an exoplanet candidate was a transit signal that hadpassed a battery of astrophysical false-positive and instrumentalfalse-alarm tests. In K2, however, the usage is looser; the term iscommonly used to refer to any exoplanet signal that a particularteam has identified as a possible planet. So long as the reasoningis sound and the results are published, the signal is effectively acandidate. A validated planet is a candidate that has been vet-ted with follow-up observations and determined quantitatively tobe far more likely an exoplanet than a false positive (accordingto some likelihood threshold). Validated planets, because confi-dence in their planethood is higher than for a regular candidate,are far more promising targets than planet candidates for follow-up observations, characterization, and eventual confirmation. Wenote that validation is not the same thing as confirmation, whichis ideally attained through a reliable mass determination. In thiswork, we are in general not attempting to “confirm” planets. Con-firmation is more rigorous than validation, in the same way thatvalidation is more rigorous than candidacy. Confirmation is usu-ally accomplished via the RV method, the TTV method, or, lesscommonly, methods such as a full photodynamical modeling so-lution (e.g. Carter et al. 2011) or Doppler tomography (e.g. Zhou
tion tool developed by Morton (2012, 2015b), finding 149to be validated with a false-positive probability (FPP)less than 0.1%. Of these newly validated exoplanets, 39were previously only exoplanet candidates and 56 havenot been previously detected. This work will increase thevalidated K2 planet sample from 212 (according to theMikulski Archive for Space Telescopes30; accessed 2018February 14) to 307, an increase of nearly 50%. Sim-ilarly, this work increases the K2 candidate sample by∼20%.
In this paper we describe the identification and anal-ysis of our candidate sample, as well as our validationprocess and the resulting validated planet sample. Sec-tion 2 discusses the process by which we use K2 data toidentify exoplanet candidates. Section 3 describes ourground-based observations of the planet candidate hoststars detected by K2. Section 4 explains the analysisof the K2 light curves and the follow-up spectroscopyand high-contrast imaging. Section 5 details how we usevespa to calculate FPPs for our planet candidates. Sec-tion 6 presents the results of the our candidate identi-fication, vetting, follow-up observations, and analysis indetail for a single, instructive planet. Then the resultsfor the entire planet candidate sample are similarly pre-sented. In Section 7, we discuss the results of our work,including confirmation of features in the exoplanet pop-ulation previously identified using data from the originalKepler mission. Finally, we summarize and conclude inSection 8.
2. PIXELS TO PLANETS
In this section, we first explain how K2 observationsare collected, then we describe the process by which sys-tematic errors are removed from K2 data, and finally wediscuss the analysis of the systematics-corrected K2 datain order to identify planet candidates.
2.1. K2 Observations
Since 2014, the K2 mission has served as the successorto the original Kepler mission. By observing fields alongthe ecliptic plane and firing its thrusters approximatelyonce every six hours, the probe can maintain an unstableequilibrium against solar radiation. However, the space-craft can only point toward a given field for roughly 83days before re-pointing (in order to keep sunlight on thespacecraft panels and out of its telescope).
Because of on-board data storage constraints, not alldata collected by the CCD array can be retained andtransmitted to the ground. As a result, targets must beidentified within each campaign field prior to observationso that non-target data can be discarded and a postagestamp (a small group of pixels) around each target canbe saved and transmitted to the ground.
In the original Kepler mission, the primary objectivewas to determine the frequency of Earth-like planets or-biting Sun-like stars (Batalha et al. 2010b). Althoughsome planet search targets were selected during missionadjustments and others were selected through a GuestObserver (GO) program for secondary science objectives,most targets were selected pre-launch for the primary ob-jective. However, K2 operates in a very different manner.
et al. 2016).30 https://archive.stsci.edu/k2/published planets/search.php
New Candidates and Planets Transiting Bright Stars 3
For each K2 campaign, targets are exclusively selectedthrough the GO program, which evaluates observing pro-posals submitted by the astronomical community for anyscientific objective, not just exoplanet-related objectives.Ideally, GO proposals have scientifically compelling goalsthat can be achieved through K2 observations and cannoteasily be achieved with other instruments or facilities.
In a typical K2 campaign, the number of targets rangesbetween 10,000 and 40,000 with long-cadence observa-tions (≈30-minute integration), and about 50-200 withshort-cadence observations (≈1-minute integration). Ex-ceptions include C0, which served primarily as a proof-of-concept campaign to show that the K2 mission wasviable, and C9, which focused on microlensing targets inthe Galactic Bulge. Both C0 and C9 had fewer targetsthan normal in both long cadence and short cadence.It should also be noted that there are occasional over-laps between campaign fields. Despite fewer new tar-gets, overlaps provide a longer baseline of observationsfor targets of interest in the overlapping region.
This paper focuses on Campaigns 0 through 10 (ex-cluding Campaign 9). However, the process implementedin this research can easily be extended and applied to ad-ditional K2 campaigns.
2.2. K2 Data Reduction
Because of the loss of two reaction wheels, the Ke-pler telescope is perpetually drifting off target and mustbe regularly corrected by thruster fires, causing shifts inthe pixels that targets fall on. These shifts, coupled withvariable sensitivity between pixels on the telescope CCDsand variable amounts of starlight falling inside photomet-ric apertures, lead to systematic variations in the signalfrom K2 targets, introducing noise into the photometricmeasurements. Howell et al. (2014) estimated that rawK2 precision is roughly a factor of 3-4 times worse thanthe original Kepler precision (depending on stellar mag-nitude). Fortunately, an understanding of the motion ofthe Kepler spacecraft allows for modeling and correctionof the induced systematic noise. In particular, we rely onthe method of systematic correction described by Van-derburg & Johnson (2014, hereafter referred to as VJ14),as well as the updates to the method described in Van-derburg et al. (2016a, hereafter referred to as V16). Webriefly describe here the method developed by VJ14.
First, 20 different aperture masks were chosen foreach target star, 10 circular masks of varying size and10 masks shaped liked the Kepler pixel response func-tion (PRF) for the target with varying sensitivity cut-offs. These masks were used to perform simple aperturephotometry to produce 20 different “raw” light curves.Then the motion of the target star across the CCD wasestimated by calculating centroid position for each ca-dence31. Next, the recurrent path of the centroid acrossthe CCD between thruster fires was identified. Data col-lected during thruster fires were identified and removed.Then, for each of the 20 raw light curves produced, low-frequency variations (> 1.5 days) were removed with abasis spline, and the relationship between centroid posi-
31 Although it is possible to produce light curves by decorre-lating with centroid positions measured from each star, we usedthe centroids measured from one hand-selected isolated, bright K2target per campaign, which we found gives better results.
tion and flux was fit with a piecewise function. Becausethe centroid path would shift on timescales longer than5-10 days, the flux-centroid piecewise function was ap-plied separately to each 5-10 day light-curve segment of5-10 days. This function was then used to correct theraw data so that low-frequency variations could be recal-culated. This process was then repeated iteratively untilconvergence. Finally, after all 20 raw light curves perstar were processed in this way, a “best” aperture waschosen to maximize photometric precision. An exampleof a light curve before and after the full data reductionprocedure can be seen in Fig. 1 for the planet host EPIC212521166. We note that light from any nearby com-panion stars could potentially enter the best aperturemask, which may lead to a diluted transit and an under-estimated planet radius (Ciardi et al. 2015; Hirsch et al.2017). However, we expected this effect to be small evenwhen present and therefore do not correct for it.
2.3. Identifying Threshold Crossing Events
AFter the roll systematics were removed from the pho-tometry according to the method described by VJ14, weconducted a transit search of each K2 target using themethod of Vanderburg et al. (2016a). We give a shortdescription of the transit search process here.
First, low-frequency variations were removed via a ba-sis spline and outliers were removed. Then a box-least-squares (BLS) periodogram (Kovacs et al. 2002) was cal-culated over periods between 2.4 hr and half the lengthof the campaign. All periodic decreases in brightnesswith a signal-to-noise ratio (S/N) > 9 were investigated.If putative transits lasted longer than 20% of their pe-riod, or were composed of a single data point, or changeddepth by over 50% when the lowest point was removed,the signal was removed and the BLS periodogram recal-culated. Any detection passing these tests was deemed athreshold-crossing event (TCE). We identified ∼30, 000TCEs across C0-C10 in this manner.
Each TCE was fit with the Mandel & Agol (2002)transit model to estimate transit parameters, then theTCE was removed from the light curve, and the BLSperiodogram was recalculated. AFter all TCEs hadbeen identified, they subsequently underwent “triage”,in which each candidate was inspected by eye in orderto remove obvious astrophysical false positives and in-strumental false alarms from subsequent analysis. TCEsidentified as neither type of false signal passed the triagephase and moved on to a “vetting” phase.
2.4. Identifying K2 Candidates
During vetting, we subjected the surviving TCEs to abattery of additional tests to identify astrophysical falsepositives and instrumental false alarms. Some of thesetests were identical or similar to the tests conducted forthe Kepler mission, while others are specific to K2 data.For each test we produced a diagnostic plot, examples ofwhich are shown in Figs. 2, 3, and 4. Here we describethe tests we conducted in more detail.
1. The times of the in-transit points of a TCE werecompared against the position of the Kepler space-craft at these times, as many instrumental falsealarms were composed of data points near the edgesof Kepler’s rolls where the K2 flat field is less well

The blue points showthe light curve before correcting for the systematics induced by the roll motion of the Kepler spacecraft, while the yellow points show thesame light curve after those systematics have been removed via the data reduction process summarized in Section 2.2 and documentedin Vanderburg & Johnson (2014) and Vanderburg et al. (2016a). The remaining downward dips in the corrected (yellow) light curve aretransits of a mini-Neptune sized exoplanet, validated in this work and previously confirmed in Osborn et al. (2017).
constrained, and our analysis method can leave insystematics. The plots we used to identify thesefalse alarms are shown in Figs. 2 and 3.
2. We compared the signal of a TCE in lightcurves produced using multiple different photomet-ric apertures. This test is a powerful way to iden-tify signals caused by instrumental systematics (asthese systematics present differently in differentphotometric apertures), as well as identifying as-trophysical false positives, such as when a candi-date transit signal was due to contamination froma nearby star. An example of these tests is shownin Fig. 3. We note that although this test rules outtransits or eclipses originating from a nearby com-panion, it does not rule out the possibility of lightcontamination from a nearby companion, whichcould dilute the observed transit and lead to an un-derestimation of the planetary radius (Ciardi et al.2015; Hirsch et al. 2017).
3. Individual transits of a TCE were visually in-spected, since instrumental false alarms were lesslikely to have consistent, planet-like transit depthsor shapes (see Fig. 2). This metric is qualitativelysimilar to the “transit patrol” metrics introduced inthe DR25 Kepler planet candidate catalog (in par-ticular the Rubble, Marshall, Chases, and Zumatests; Thompson et al. 2017).
4. Flux-centroid motion, phase variations (possiblycaused by relativistic beaming, reflected light, orellipsoidal effects), differences in depth betweenodd- and even-numbered transits, and secondaryeclipses were all searched for as evidence of astro-physical false positives. Similar tests have beenused since the beginning of the Kepler mission
(Batalha et al. 2010a). Example diagnostic plotsfor identifying phase variations, the difference be-tween even- and odd-numbered transits, and sec-ondary eclipses near phase 0.5 are shown in Fig. 2;flux-centroid shift tests are shown in Fig. 3. Wesearched for secondary eclipses at arbitrary phases(not necessarily near phase = 0.5) using the model-shift uniqueness test designed by Coughlin et al.(2016). We show diagnostic plots for the model-shift uniqueness test in Fig. 4.
5. We searched for astrophysical false-positive scenar-ios by ephemeris matching. Sometimes the pixelssurrounding a target star can be contaminated witha small amount of light from other nearby stars.When those nearby stars are variable themselves(like eclipsing binaries), the variability from thenearby stars can be introduced into the target’slight curve (Coughlin et al. 2014). We identifiedcases where this happened by searching for planetcandidates that have the same period (or integermultiples of the same period) and time of transitas eclipsing binaries observed by K2 using the samecriteria as Coughlin et al. (2014). We found no ex-amples of matched ephemerides due to direct PRFoverlap that we had not also identified in our testswith multiple photometric apertures, but we didfind two instances where candidate transit signalswere caused by charge transfer inefficiency alongone of the columns of the Kepler detector. We ex-cluded a candidate around EPIC 212435047 causedby contamination from the eclipsing binary EPIC212409377 located along the same CCD columnabout 2000 arcsec away, and we excluded a can-didate around EPIC 202710713 contaminated bythe eclipsing binary EPIC 202685801 located along
New Candidates and Planets Transiting Bright Stars 5
the same CCD column at a distance of about 300arcsec.
6. We estimated the S/N of a TCE by taking the dif-ference between the mean baseline flux and the in-transit flux and dividing by the quadrature sum ofthe standard deviation of the flux in those two re-gions. We defined the boundaries of the in-transitregion in two ways and calculated the S/N for bothchoices. In one case we used every data point col-lected between the second and third contact (mi-nus a single long-cadence Kepler exposure on eitherside). This estimate of S/N could sometimes not becalculated if the transit was grazing. In the othercase we used the central 20% of data collected fromthe first to fourth contact (which could be calcu-lated even if the transit was grazing). Followingstandard practice from the Kepler mission, if bothof these values (or just the latter in the grazingcase) were below 7.1σ the candidate was excluded(7.1σ is the minimum significance level for a signalto qualify as a TCE in the Kepler Science Pipeline;Jenkins et al. 2010). We only encountered two suchcandidates: EPIC 220474074 and EPIC 201289302.
Although it is possible to automate diagnostic testsof this type (see, for example, the Robovetter that wasdesigned for the main Kepler mission; Coughlin et al.2016), we performed vetting tests 1-4 by eye.
Any TCE surviving all of these vetting stages was pro-moted to planet candidate (∼1, 000 were promoted inthis way). All candidates orbiting sufficiently bright hoststars (see Section 3.1) were then subjected to our valida-tion process.
3. SUPPORTING OBSERVATIONS
In this section, we describe the follow-up observa-tions we conducted to better characterize the candidatehost stars. These observations are crucial for improv-ing stellar parameters (e.g. Dressing et al. 2017a; Mannet al. 2017; Martinez et al. 2017), which in turn canhelp differentiate between a transiting planet and var-ious false-positive scenarios (i.e. stellar binary configu-rations) that might prefer different regions of stellar pa-rameter space. We first discuss high-resolution opticalspectroscopy of the planet candidate host stars from theTillinghast Reflector Echelle Spectrograph (TRES), fol-lowed by speckle imaging from the Differential SpeckleSurvey Instrument (DSSI) and the NASA Exoplanet Starand Speckle Imager (NESSI) at the WIYN telescope,32
the Gemini South telescope, and the Gemini North tele-scope, and finally, adaptive optics (AO) imaging fromKeck Observatory, Palomar Observatory, Gemini SouthObservatory, Gemini North Observatory, and the LargeBinocular Telescope Observatory.
3.1. TRES Observations
All of the spectra used in this work were obtainedwith TRES, a spectrograph with a resolving power ofR = 44, 000 and one of two spectrographs for the 1.5
32 The WIYN Observatory is a joint facility of the Universityof Wisconsin-Madison, Indiana University, the National OpticalAstronomy Observatory, and the University of Missouri.
m Tillinghast telescope at the Whipple Observatory onMt. Hopkins in Arizona. We obtained at least one us-able TRES spectrum of each of the planet candidate hoststars that we consider in this work and that we subject toour validation process (see Section 4.2 for our definitionof “usable”). With a few exceptions, we only observedcandidates brighter than 13 mag in the Kepler band withTRES because of the lengthy integration time requiredto collect spectra of stars fainter than this and the diffi-culty of subsequent follow-up observations (for example,with precise radial velocities) at other facilities. Thislimitation reduced the number of candidates we consid-ered for validation significantly, from ∼1, 000 to 275. Inthe future, observing these fainter candidates, either withTRES or other spectrographs on larger telescopes, couldpotentially more than double the number of K2 planetsfor our analysis.
3.2. Speckle Observations
We observed many of our planet candidates withspeckle imaging from either the 3.5 m WIYN telescope,the Gemini-South 8.1 m telescope, or the Gemini-North8.1 m telescope. Together, the three telescopes collected162 speckle images of 73 stars with DSSI (Horch et al.2009). DSSI is a speckle-imaging instrument that travelsbetween different telescopes. For each of the 73 targets,we collected DSSI speckle images at narrowband filterscentered at 6920 and 8800 A (at least one of each forevery target). These observations were made in 2015September and October, as well as in 2016 January,April, and June.
Furthermore, 160 speckle images were collected for adistinct sample of 70 stars at the WIYN telescope us-ing NESSI, which is essentially a newer version of theDSSI instrument. For each of the 70 targets, we collectedNESSI speckle images at narrowband filters centered at5620 and 8320 A (at least one of each). These observa-tions were made in 2016 October through November and2017 March through May. A list of the observed starscan be found in Table 7.
3.3. AO Observations
In addition to speckle imaging, we also observed manyof our planet candidate host stars with AO imaging.
We collected 47 AO images for 45 stars on the KeckII 10 m telescope in K filter with the Near Infra RedCamera 2 (NIRC2); 5 of these stars were also imagedusing NIRC2 in J band. All of these observations weremade during 2015 April, July, August, and October aswell as 2016 January and February.
We collected 27 AO images for 27 stars on the Palomar5.1 m Hale telescope in K filter with the Palomar HighAngular Resolution Observer (PHARO, Hayward et al.2001); 6 of these stars were also imaged using PHAROin J band. All of these observations were made during2015 February, May, and August as well as 2016 June,September, and October.
We collected 19 AO images for 18 stars on the Gemini-North 8.1 m telescope in K band with the Near InfraRedImager and spectrograph (NIRI, Hodapp et al. 2003).These observations were made during 2015 October andNovember as well as 2016 June and October.
We collected a single AO image on the Large Binocu-lar Telescope in K filter with the L/M-band mid-infrared

Camera (LMIRCam, Leisenring et al. 2012). This obser-vation was made in 2015 January.
There was some overlap between instruments; overall,AO images were collected for a total of 80 systems. Alist of the observed stars can be found in Table 7.
4. DATA ANALYSIS
After all of the photometry had been reduced and all ofthe necessary follow-up observations had been collected,the next step was to analyze the data, calculate relevantparameters, and prepare the results for the validationprocess. In this section, we explain the process of fittinga model to our reduced light curves (to determine transitparameters and create folded light curves), analyzing ourspectra (to calculate stellar parameters), and extractingand reducing data from our high-contrast images (to cre-ate contrast curves).
4.1. K2 Light Curves
4.1.1. Simultaneous Fitting of K2 Systematics and TransitParameters
In Sections 2.2, 2.3, and 2.4 we described the processof correcting K2 photometry for instrumental systemat-ics and exploring the reduced light curves for candidates.After these steps were completed, the planet candidatesneeded to be more thoroughly characterized. In order toassess transit and orbital parameters, we reproduced theK2 light curves for these planet candidates by rederivingthe systematics correction while simultaneously model-ing the transits in the light curve. As in our originalsystematics correction, the light curve was divided intomultiple sections and the systematics correction was ap-plied to each section separately. A piecewise linear func-tion was fit with breaks roughly every 0.25 arcsec (vary-ing slightly by target) to the arclength versus brightness

Left column, first (top), second, and third rows: images from the first Digital SkySurvey, the second Digital Sky Survey, and K2 respectively, each with a scale bar near the top and an identical red polygon to show theshape of the photometric aperture chosen for reduction. The K2 image is rotated into the same orientation as the two archival images(north is up). Middle column, top row: multiple panels of uncorrected brightness versus arclength, chronologically ordered and separatedinto the divisions in which the roll systematics correction was calculated. In-transit data points are shown in red, orange points denotethe brightness correction applied to remove systematics. Middle column, bottom row: variations in the centroid position of the K2 image.In-transit points are red. The discrepancy (in standard deviations) between the mean centroid position in transit and out-of-transit isshown on the right side of the plot. Right column, first row: the K2 light curve near transit as calculated using three differently sizedapertures: small mask (top panel), medium mask (middle panel), and large mask (bottom panel), each with the identical best-fit model inred. Aperture-size dependent discrepancies in depth could suggest background contamination from another star. Right column, third row:the K2 image overlaid with the three masks from the previous plot shown (in this figure, the large mask is fully outside the postage stampand is therefore not visible).
relationship described in section 2.2 (arclength is a one-dimensional measure of position along the path an imagecentroid traces out on the Kepler CCD camera). Thelow-frequency variations in the light curve were modeledwith a cubic spline (with breakpoints every 0.75 days),and the transits themselves were modeled with the Man-del & Agol (2002) transit model. The fit was performedusing a Levenberg-Marquardt optimization (Markwardt2009), and all of the parameters from the optimization(besides the transit parameters) were used in order tocorrect the systematics of the light curve (once again)and remove the low-frequency variations (once again).Since these parameters were determined in a simulta-neous fit with the transits, the quality of the resultinglight-curve reduction tended to be better than that ofthe original light curves.
4.1.2. Final Estimation of Transit Parameters andUncertainties
After we produced the systematics-corrected, low-frequency-extracted light curves, we analyzed them fur-
ther in order to estimate final transit parameter valuesand their uncertainties. We based our model on theBATMAN Python package (Kreidberg 2015), which we usedto calculate our synthetic transit light curves. We fitthe transit light curves of all planet candidates arounda given star simultaneously so that overlapping transitscould be modeled, assuming that each of the planets werenon-interacting and on circular orbits. For each planetcandidate, five parameters were included: the epoch (i.e.time of first transit), the period, the inclination, the ra-tio of planetary to stellar radius (Rp/R∗), and the semi-major axis normalized to the stellar radius (a/R∗). Addi-tionally, two parameters for a quadratic limb-darkeninglaw were included (Kipping 2013), as well as a parameterto allow the baseline to vary (in case there was an erro-neous systematic offset from flux = 1 outside of transit),and a noise parameter that assigned the same uncertain-ties to each flux measurement (since flux error bars werenot calculated in the K2 data reduction process). Forall of these planet and system parameters we assumed a

Figure 4. Model-shift uniqueness diagnostic plots for EPIC 212521166.01. We cross-correlated the phase-folded light curve of each planetcandidate with the candidate’s best-fitting transit model for the candidate. The two plots in the top row show the cross-correlation functionas a function of orbital phase with different scaling on the Y-axis. The tallest peak in the response is the primary transit, and the threevertical lines show the phase of the highest significance putative secondary event (red) , the second-highest significance putative secondaryevent (orange), and the highest significance upside-down secondary event (blue). The bottom row of plots show the three segments of thelight curve surrounding the highest and second-highest significance putative secondary eclipses, and the highest significance upside-downevent. Gray and purple data points are unbinned and binned observations, respectively. Comparing the amplitudes of these three eventsgives an indication of their significance. Here, the two most significant putative secondary eclipses have a similar amplitude to the mostsignificant upside-down event, indicating that they are all likely spurious. We find no significant secondary eclipse in the light curve ofEPIC 212521166.01.

uniform prior, except for the Rp/R∗ parameter for eachplanet, which we gave a log-uniform prior.
For each candidate system, the transit parameters
in this model were estimated using emcee (Foreman-Mackey et al. 2013), a Python package that runs simula-tions using a Markov chain Monte Carlo (MCMC) algo-rithm with an affine-invariant ensemble sampler (Good-man & Weare 2010). In each simulation, the parameterspace for a system with n candidates was sampled with8 + 10n chains (equal to twice the number of model pa-rameters). The MCMC process was run for either 10,000steps or until convergence, whichever came last. Con-vergence was defined according to the scale-reductionfactor (Gelman & Rubin 1992), a diagnostic that com-pares variance for individual chains against variance ofthe whole ensemble. A simulation was considered con-verged when the scale-reduction factor was less than 1.1for each parameter. The Gelman-Rubin scale-reductionfactor is properly defined for chains from distinct, non-communicating MCMC processes; however, we foundthat our simulations visually converged many times morequickly than the Gelman-Rubin diagnostic, so we decidedthe diagnostic would be sufficient for our purposes. Anexample of a converged model fit against transit data canbe seen in Fig. 5.
Additionally, each simulation was checked after theminimum number of steps (10,000) and at the end ofthe simulation for any chains in the ensemble that couldbe easily categorized as “bad,” i.e. trapped in a mini-mum of parameter space with a poorer best fit than theminimum of the ensemble majority. In detail, a chain
New Candidates and Planets Transiting Bright Stars 9
was classified as “bad” if both of the following applied:
1. The Kolmogorov-Smirnov statistic between thechain with the highest likelihood step and the chainin question was greater than 0.5.
2. θl/θg < 1/(100n), where θl is the local maxi-mum likelihood (the maximum likelihood withinthe chain in question), θg is the global maximumlikelihood throughout the ensemble, and n is the to-tal number of steps. This test is our own invention,which is more likely to classify a chain as bad whenits maximum likelihood is farther from the globalmaximum likelihood. This test also accounts forthe length of the simulation, since the maximumlikelihood within each chain should be closer to theglobal maximum likelihood for longer simulations.We include a factor of 100 in the denominator tomake the test sufficiently conservative, such thatit only finds bad chains very rarely and only thoseextremely unlikely to rejoin the ensemble in thelifetime of the simulation.
If a chain was deemed bad after 10,000 steps, its posi-tion in parameter space was updated to that of a goodchain from the previous step of the simulation. If a chainwas deemed bad at the end of the simulation, it was sim-ply removed and not replaced. Both after 10,000 stepsand at the end of the simulation, bad chains only oc-curred about 15% of the time, typically for only one ortwo chains in the ensemble.

4.2. TRES Spectroscopy
We first visually inspected each of the spectra collectedwith TRES for our candidate host stars. Our main goalin visually inspecting the spectra was to identify cases inwhich the spectra were composite or otherwise indicativeof multiple stars in the system. We looked at diagnos-tic plots produced by the TRES pipeline, which showedvarious echelle orders and a cross-correlation between asynthetic template spectrum and a single spectral orderaround 5280 A.
After identifying composite spectra and confirmingthat the others were apparently single-lined, we preparedthe spectra before determining the host stars’ parame-ters. In particular, we manually removed cosmic raysfrom the spectra that might bias or otherwise affect thespectroscopic parameters we measured. We focused onthree echelle orders in particular, orders 22, 23, and 24(covering 5059-5158, 5135-5236, and 5214-5317 A, re-spectively), which are within the range we used to mea-sure spectroscopic parameters.
After we visually inspected each spectrum and remov-ing cosmic rays, we analyzed each TRES spectrum usingthe Stellar Parameter Classification (SPC) tool, devel-oped by Buchhave et al. (2012). SPC determines keystellar parameters through a comparison of the inputspectrum (between 5050 and 5360 A) to a library gridof synthetic model spectra, developed by Kurucz (1992).The library is 4-dimensional, varying in effective temper-ature Teff , surface gravity log g, metallicity [m/H], and
line broadening (a good proxy for projected rotational ve-locity, or v sin i). [m/H] is estimated rather than [Fe/H]because all metallic absorption features are used to de-termine metallicity rather than just iron lines. (SPC as-sumes that all relative metal abundances are the same asin the Sun, and [m/H] simply scales all solar abundancesby the same factor.) This library grid spans Teff from3500 K to 9750 K in 250 K increments, log g from 0.0 to5.0 (cgs) in 0.5 increments, [m/H] from -2.5 to +0.5 in0.5 dex increments, and line broadening from 0 km s−1
to 200 km s−1 in progressively spaced increments (from1 km s−1 up to 20 km s−1). In total, the library contains51,359 synthetic spectra. The stellar parameters derivedusing SPC can be found in Table 5.
We also calibrated TRES against Duncan et al. (1991)for the SHK stellar activity index, a measure of thestrength of emission in the cores of the H and K CaII spectral absorption features. Our calibration was onlyperformed over a range of 0.244 < B-V < 1.629, 0.055 <SHK < 2.070, and v sin i < 20 km s−1. Additionally, werequired a photon count of more than 250,000 in the Rand V continuum regions (3901.07±10 A and 4001.07±10A, respectively). Within these ranges, we were able tocalculate SHK for 28 of our spectra collected for fourstars. Although there are relatively few K2 planet can-didates bright enough for this measurement on a 1 mtelescope, it will be much more common with the Ter-restrial Exoplanet Survey Satellite (TESS). A note hasbeen made for the relevant stars in Table 5 and the fullresults are listed in Table 3. There is also a detailed de-scription of the SHK calibration process for TRES in theAppendix.
In cases where we observed a candidate host star morethan once with TRES, we attempted to identify or ruleout large velocity variations indicating a stellar compan-ion to the host star. (For this purpose we collected onenew TRES spectrum each for EPIC 220250254 and EPIC210965800, but otherwise exclusively used the spectrafrom which we derived stellar parameters.) We phasedthe radial velocities to the photometric ephemeris and fita sinusoid to the velocities at the period and ephemeris ofeach candidate (and assuming a circular orbit) in orderto estimate the companion mass and mass uncertainty.If the companion mass was more than 3σ lower than 13Jupiter masses, we ruled out the eclipsing binary scenario(see Section 5.1). If the semi-amplitude of the compan-ion mass was more than 1 km s−1 we labeled the systemas a binary. Five systems were labeled binaries in thismanner. If neither of the above cases was true, no actionwas taken.
Out of the 233 candidate host stars, 43 had more thanone TRES spectrum available. The stellar parameterscalculated for the spectra of such candidates were com-bined via a weighted average based on the peak heightof the cross-correlation function. The scatter betweenmultiple spectra for the same candidate was not largerelative to the assumed systematic errors. For example,Buchhave et al. (2012) set an internal error floor of 50 Kfor effective temperature; we found an average standarddeviation of 40 K between spectra of the same candidate,and the scatter was less 100 K for ∼90% of candidateswith multiple spectra.
There were some instances in which a TRES spectrum
10 Mayo et al.
was not considered good enough for stellar parameterestimation with SPC. In particular, we did not use anyspectrum for which the S/N per resolution element was< 20 or the cross-correlation function peak height of thespectrum was < 0.8. Furthermore, we also did not useany spectra that yielded SPC results outside of certaintrustworthy ranges. Specifically, we only used spectrathat yielded 4250 < Teff < 6500 and line broadening< 50 km s−1. It should also be noted that all spectraused to determine stellar parameters were collected withTRES on or before 2017 June 10 (although some usablespectra have since been collected, they were not retroac-tively included in our stellar parameter analysis). Noplanet candidate underwent the validation process un-less their host star had at least one spectrum (collectedwith TRES) that satisfied these criteria.
4.3. Contrast Curves
We quantified the constraints placed on the presenceof additional companions in our high-resolution (speckleand AO) imaging by calculating contrast curves. A con-trast curve specifies at a given distance from the targetstar how bright a companion star would have to be inorder to be detected.
After the speckle observations were collected, the datawere reduced according to the method described inFurlan et al. (2017), yielding a high-contrast image ofa candidate. Then local minima and maxima were ana-lyzed relative to the star’s peak brightness to determine∆m (average sensitivity) and its uncertainties withinbins of radial distance from the target star. The contrastcurves used in this research were the 5σ upper limit on∆m as a function of radial distance. A more detaileddescription of the data reduction process can be foundin Howell et al. (2011). An example of a contrast curvecan be seen in Fig. 6.
As for AO observations, the creation of correspondingcontrast curves was performed by injecting fake sourcesinto the images and varying their brightness in order todetermine the brightness threshold for the detection al-gorithm being used. This process is described in greaterdetail in Crossfield et al. (2016) and Ziegler et al. (2017)
Note that these processes of creating a contrast curvewere the same regardless of wavelength. So in the in-stances that multiple speckle or AO images at differentwavelengths were available, multiple contrast curves werecreated that were all used in the validation process for agiven candidate.
5. FALSE-POSITIVE PROBABILITY (FPP) ANALYSIS
5.1. The Application of vespa to Planet Candidates
Our validation work relied primarily on a methodcalled validation of exoplanet signals using a probabilis-tic algorithm, or vespa, a public package (Morton 2015b)based on the work of Morton (2012). It operates withina Bayesian framework and calculates the FPP, the prob-ability that a candidate is an astrophysical false positiverather than a true positive (i.e. a planet).
After photometry, spectroscopy, and any availablehigh-contrast imaging had been collected and reducedfor a candidate system, that system underwent our val-idation procedure using vespa. For each candidate, thefollowing information was supplied:
1. A folded light curve containing the planetary tran-sit and roughly one transit duration of baseline oneither side. Identical error bars were assigned toall data points based on the noise parameter deter-mined by our transit-fitting procedure. From thislight curve, other planets in the system were re-moved using the best-fit parameters determined bythe fitting procedure.
2. A secondary threshold limit. We calculated thislimit by first cutting out all transits from all can-didates in a system. Then, for a given candidate,we phase-folded the data to the candidate’s period,binned the baseline flux according to the transitduration of the candidate, calculated the standarddeviation between the bin averages, and multipliedby three. Effectively, we assert that a secondaryeclipse has not been detected at a 3σ level or higher.
3. A contrast curve. When available, this loweredthe FPP by eliminating the possibility of bound orbackground stars above a certain brightness at agiven projected distance, thus reducing the param-eter space in which a false-positive scenario couldexist. Note that vespa does not require a con-trast curve to operate, and in many cases, a candi-date host star had no contrast curve data available.However, contrast curves were collected from AOor speckle data and provided to vespa for 186 ofour 233 candidate host stars (see Table 7).
4. R.A. and Decl. The likelihood of a false-positivescenario is calculated by vespa based on the targetstar’s location on the celestial sphere. For example,near the Galactic plane, a target star’s FPP willincrease significantly due to the crowded field.
5. Teff , log g, and [m/H] (collected from SPC). Theseconstraints help rule out false-positive scenariosthat would otherwise be allowed given only stellarmagnitude information. Although vespa could op-erate without these values, we did not apply vespato any candidate system for which stellar parame-ters could not be estimated from a TRES spectrum.
6. Stellar magnitudes. The K2 Ecliptic Plane InputCatalog (Huber et al. 2016) was queried to findmagnitude information on each target star in theKepler, J , H, and K bandpasses. The J , H, andK bandpasses originated from the 2MASS catalog(Cutri et al. 2003; Skrutskie et al. 2006). Mag-nitude uncertainties were not required or providedfor the Kepler bandpass, while uncertainties for theJ , H, and K bandpasses were added in quadraturewith 0.02 mag of systematic uncertainty to be con-servative.
7. Parallaxes. When parallaxes were available fromHIPPARCOS (Perryman et al. 1997) or GAIA(Gaia Collaboration et al. 2016a,b), they were alsoincluded.
With all this input, vespa makes a representative pop-ulation for each false-positive scenario (and the transitingplanet scenario). False-positive scenarios considered by

vespa include a background (or foreground) eclipsing bi-nary blended with the target star, a hierarchical eclipsingbinary system, or a single eclipsing binary system (as wellas each of those scenarios with twice the period). Thenvespa calculates a prior for each scenario by multiplyingtogether the probability that the scenario exists withinthe photometric aperture, the geometric probability thatthe scenario leads to an eclipse, and the fraction of in-stances in which the eclipse is appropriate. Here “ap-propriate” means that an instance’s eclipse takes placewithin the photometric aperture, the secondary eclipse(if it exists) is not deep enough to cross the detectionthreshold, the instance’s primary star has wavelength-dependent magnitudes within 0.1 mag of those providedas input, and the instance’s primary star has Teff andlog g that agree with the input values to within 3σ.
Then the likelihood for each scenario is calculated us-ing the folded light curve by fitting against a distributionof transit durations, depths, and ingress/egress slopescalculated from each scenario. When the priors and like-lihoods have been determined for each scenario, the laststep is simply to combine them for each scenario in orderto determine an overall posterior likelihood for every sce-nario. If the posterior likelihood for the planet scenariois exceedingly higher than all of the other scenarios com-bined, then the candidate can be classified as a validatedplanet. In our case, we required the sum of all false-positive scenario probabilities to be < 0.001.
The output from vespa includes simulation informa-tion from the underlying light-curve fitting process, aswell as figures and text files conveying likelihood infor-mation of various false-positive scenarios and the tran-siting planet scenario. Section 6.1 provides a con-crete validation example with characteristic input andoutput. Additionally, the full vespa input and out-put for each exoplanet candidate has been archived athttps://zenodo.org/record/1164791.
As we noted in Section 4.2, for systems where we hadcollected more than one good TRES spectrum, we phasedthe RVs to search for or eliminate the possibility of aneclipsing binary scenario. (Small RVs would not ruleout hierarchical or background eclipsing binary scenar-ios since large RVs would be reduced by the third starin the aperture.) In cases where the eclipsing binary sce-nario could be eliminated, we reduced the probability ofthe scenario (and the similar scenario analyzed by vespawith double the period) to zero. We then divided theprobability of all the remaining scenarios investigated byvespa by their sum so that the total probability was stillone.
Systems with multiple planet candidates are morelikely to be hosting multiple planets than multiple false-positive signals. In fact, the likelihood of the planetscenario for each individual candidate is consequentlyboosted relative to false-positive scenarios in multiplanetcandidate systems (Latham et al. 2011). To accountfor this effect, we apply a “multiplicity boost” to theplanet scenario prior in such systems, deflating the FPPby the multiplicity boost factor to account for the na-ture of these systems. We choose a boost factor of 25 fordouble-candidate systems and a boost factor of 50 for sys-tems with three or more candidates based on the valuesused by Lissauer et al. (2012), Vanderburg et al. (2016b),and Sinukoff et al. (2016). The FPP values reported in
Table 4 already have the appropriate multiplicity boostfactor applied.
5.2. Criteria for Planet Validation
Following standard practice, we only validated planetsfor which the following were true, since vespa assumeswe have checked for and ruled out each of them:
1. There is not a composite spectrum.
2. There is not a companion in the aperture. (Thiswas determined from archival imaging.)
3. There is not a companion in AO and/orspeckle images. (This was determined fromour AO and speckle images as well as fromany images for our candidates uploaded tohttps://exofop.ipac.caltech.edu/k2/ before 2017August 9.)
4. There is no evidence of a secondary eclipse (at anyarbitrary phase).
5. There is not an ephemeris match (see Section 2.4).
If any of the above were false, the FPP was not re-ported in Table 4 and the candidate was not validatedregardless of the FPP value vespa provided.
It is worth noting that six validated planets have re-cently been shown to be false positives by follow-up ob-servations and analysis (Cabrera et al. 2017; Shporeret al. 2017). We briefly examine whether these instancesare a cause for concern in our own results.
In the case of Cabrera et al. (2017), they found thattwo false positives exhibited increased transit depths forlarger aperture masks (suggesting that a nearby star wasresponsible for the eclipses), while the third showed a sec-ondary eclipse at phase = 0.62 when they used a differ-ent data reduction process. The first two false positiveswould have failed the variable-sized mask test we ap-ply via our diagnostic plots, while the secondary eclipsefrom the third false positive would have been caughtthrough a combination of our data reduction process andthe model-shift uniqueness test we apply (Coughlin et al.2016).
As for Shporer et al. (2017), the vespa fit to the avail-able photometry for each false positive was very poorand all three of the false positives were reported to bevery large “planets.” We addressed these concerns in twoways. First, we decided to only use 2MASS photometryin order to avoid systematic errors between photometricbands. Second, we chose not to validate any planet can-didates larger than 8 R⊕, since a candidate of that sizeor larger could actually be a small M dwarf. The only ex-ception to this rule is if there are RV measurements thatcan rule out the eclipsing binary scenario, in which casewe do report the FPP (and validate for FPP < 0.001),regardless of planet size.
6. RESULTS
The results section is divided into two parts. In thefirst part, the process of validation is described in detailfor a single planet candidate, in order to explain preciselyhow the photometry and follow-up observations are used.In the second part, our validation process is more widelyapplied to every selected candidate, and the results foreach candidate are reported.

6.1. Validating a Single Planet: EPIC 212521166.01
In order to understand the process that was applied toeach of our candidates, it is instructive to look at valida-tion for a single, concrete example. Here, we describe indetail the validation process for a typical planet candi-date system, EPIC 212521166 (K2-110). We chose thissystem because (1) it was detected in our pipeline, and(2) Osborn et al. (2017) have already confirmed and char-acterized the planet, which allows us to compare some ofthe system parameters we calculated with their results.
EPIC 212521166 was observed by K2 during Campaign6. After we produced a light curve from calibrated K2pixel data and removed systematics (as described in Sec-tion 2.2), we searched for transits in our processed lightcurve (as described in Section 2.3). Our transit searchpipeline detected a single TCE with a high S/N, a pe-riod of 13.87 days and a depth of about 0.1%. Thesignal passed triage (see Section 2.3) and moved on tovetting (see Section 2.4). We confirmed that the signalwas transit-like, and observed no significant secondaryeclipse, phase variations, differences in depth betweenodd and even transits, aperture-size dependent transitdepths, or other indications of a false positive or instru-mental false alarm (see Figs. 2, 3, and 4). As a result,we promoted the EPIC 212521166 TCE to a planet can-didate.
Upon its identification as a planet candidate, we ob-served EPIC 212521166 with the TRES spectrograph onthe Mt. Hopkins 1.5m Tillinghast reflector and with the
DSSI speckle-imaging camera on the 3.5 m WIYN tele-scope at Kitt Peak National Observatory. Using the or-bital and transit parameters determined with our tran-sit model, the stellar parameters derived from SPC, afolded light curve of the planetary transit, and two con-trast curves in r band and z band collected via high-contrast speckle imaging from DSSI on the WIYN tele-scope (see Fig. 6), vespa was employed to determine theFPP for EPIC 212521166.01. The FPP was found to be8.44×10−7, which was well below the cutoff threshold, sothe planet candidate was classified as validated. The keyoutput figure of vespa can be seen in Fig. 7.
Like us, Osborn et al. (2017) found EPIC 212521166 tobe a metal-poor K-dwarf star hosting planet candidatewith P = 13.9 day and Rp = 2.6 R⊕. A comparisonof planetary and system parameters can be see in Table1. Our analyses and theirs are in good agreement forall parameters. Additionally, Osborn et al. (2017) tookthe further step of obtaining precise RV observations toconfirm the existence of EPIC 212521166.01, so we canbe confident that in this case, the assessment by vespaofa low FPP was well justified.
6.2. Full Validation Results
The process of validation described for EPIC212521166.01 in the previous section was similarly ap-plied to the remaining candidates suitable for validation.We identified 275 candidates in 233 systems that hadat least one usable TRES spectrum, and the FPP was

Figure 7. False-positive Probability analysis of EPIC 212521166.01. HEB, EB, and BEB refer to a hierarchical eclipsing binary, eclipsingbinary, and background eclipsing binary scenario, respectively. Combining the prior likelihood of a false-positive scenario (given sky position,contrast curve data, and wavelength-dependent magnitudes), as well as the likelihood of the transit photometry under various scenarios,the posterior distribution highly favors the planet scenario, with FPP = 8.44×10−7. (Note: the true FPP value is always reported in asupplementary file, but for FPP < 1 in 1e6, the figure produced by vespa simply reports the FPP as < 1 in 1e6.)
New Candidates and Planets Transiting Bright Stars 15
calculated for each of these candidates (see Table 4).Occasionally, vespa failed to return an FPP; in
such cases, the lowest data point in the light curvewas removed (to aid the initialization process for thevespatrapezoidal transit fit), and vespa was rerun. Thisapproach worked in most cases, but if it failed, the low-est two data points were removed and vespa was rerun.If that was also unsuccessful, then the FPP was not re-ported. (Most of the time, vespa only failed after thesesteps because of a Roche lobe overflow error.) 149 candi-dates in 111 systems had an FPP < 0.001 and were thuspromoted to validated planet status.
To date, the largest single release of K2 validation re-sults has been Crossfield et al. (2016), with 197 candi-dates and 104 validated planets in C0-C4. In comparison,108 of our candidates are from C0-C4, 69 of which arevalidated. The two samples share 53 candidates in com-mon, 37 of which are validated and 9 of which remaincandidates in both analyses. (Additionally, 2 candidatesin common are only validated in this work, while 5 areonly validated in Crossfield et al. 2016). This leaves 55candidates in our C0-C4 sample (30 of which are vali-dated) that were undetected by Crossfield et al. (2016),as well as 146 candidates (62 of which are validated) inthe Crossfield et al. (2016) sample that are undetected inour own C0-C4 sample. Only ∼21% of the total candi-dates were detected by both analyses, and only ∼26% ofthe total validated planets were validated by both anal-yses.

The sample overlap may seem surprisingly small, but itmakes more sense when the candidate selection and val-idation processes are examined. For example, Crossfieldet al. (2016) only considered candidates with 1 day < P< 37 day (19% of our C0-C4 sample was outside thatrange), and we only considered candidates with Kp < 13(48% of their sample was outside that range). If we onlyconsider C0-C4 candidates within those ranges (137 to-tal), both teams find over half of each other’s samples,and the overlap between samples rises to 39% (53 can-didates). Similarly, for validated planets within theseranges (77 total), both teams find more than two-thirdsof each other’s samples, and the overlap between samplesrises to 57% (44 validated planets).
There are many further examples of differences thatcreated discrepancies between the two samples. We re-quired that each planet candidate had at least one usable
TRES spectrum (see Sections 3.1 and 4.2), even thoughin early campaigns, TRES spectra were not collectedfor all bright candidates. This led to the exclusion ofmany otherwise promising candidates that are includedin Crossfield et al. (2016). Further discrepancies couldhave arisen from the temperature and planet radius cutsapplied to our validated planet sample, the eliminationof objects with companions closer than 4” in the Cross-field et al. (2016) candidate sample, and a difference insignificance thresholds for TCEs (we used 9σ while theyused 12σ).
Table 2 compares the candidate dispositions found inthis work with their previous dispositions (according tothe NASA Exoplanet Archive33 and the Mikulski Archivefor Space Telescopes34; both accessed 2018 February 14).We should note that 15 of our candidates were not val-idated in this work even though they have been previ-ously validated elsewhere. However, all of these candi-dates were either restricted from being validated by ourconservative criteria for validation (see Section 5.2), orhad an FPP value close to our validation cutoff of FPP =0.001, or were validated using different or additional ob-servations as input to vespa. We also note that our workclassifies two targets that have previously been labeled asfalse positives: EPIC 202900527.01 (K2-51 b) and EPIC210894022.01 (K2-111 b). Shporer et al. (2017) clearlyshowed EPIC 202900527.01 to be a stellar binary. Wedo not claim otherwise by labeling it a candidate (sincewe label all targets with FPP > 0.001 as candidates).On the other hand, Crossfield et al. (2016) previouslyidentified EPIC 210894022.01 as a false positive, but asubsequent, improved vespa run showed the target to infact be a planet (I. Crossfield 2017, private communica-tion). Therefore we do claim this target to be validated.
Another case worth mentioning is the multiplanet sys-tem EPIC 228725972, which hosts one validated planetand one candidate ruled out by a companion in the aper-ture and in a NESSI speckle image. The smallest aper-ture mask we tested excluded the companion (locatedapproximately 12 arcsec from the primary), but only ex-hibited transits for one of the candidates, hence the dif-ference in flags for the two candidates.
In addition to the FPPs and other parameters de-rived through the validation process described in pre-vious sections, we also calculated the radii and masses ofthe stars in our sample (the stellar radius allowed us tocalculate the absolute planetary radius). We calculatedthese parameters by inputting stellar effective tempera-ture, metallicity, and surface gravity into the isochronesPython package (Morton 2015a). We also found that in-putting 2MASS photometry into isochrones along withthe aforementioned stellar parameters had no notice-able effect on the resulting stellar radius and mass val-ues (or their uncertainties). Although isochrones havebeen found to underestimate stellar radii before (Dress-ing et al. 2017a; Martinez et al. 2017; Dressing et al.2017b), this effect is confined to M dwarfs and late-Kdwarfs, which are largely excluded from our host starsample since we do not consider stars with effective tem-peratures below 4250 K (see Section 4.2). The derivedstellar masses and radii are reported in Table 4. (We

also note that all stellar parameters for each system arereported in Table 5.)
7. DISCUSSION
7.1. Lessons Learned
There have been a few recent instances of false-positivemisclassification (Cabrera et al. 2017; Shporer et al.2017), in which a target has been classified as a validatedplanet but was later shown to be a false positive throughsubsequent analysis. Here, we discuss some of the pitfallsof statistical validation, and share some lessons we havelearned and solutions we have implemented to preventfalse-positive misclassification.
First, spectroscopy is key. Stellar parameters are cru-cial to understanding the host star and correctly classify-ing the candidates. For example, identifying the star ashighly evolved can prevent an orbiting brown dwarf or Mdwarf from being incorrectly labeled as a smaller planetorbiting a main-sequence star. One might attempt toavoid this issue by estimating stellar surface gravity viaphotometry alone, but that is notoriously difficult to doand can lead to incorrectly estimated stellar parameters.Collecting at least one spectrum from which to estimatespectroscopic parameters (including surface gravity) canavoid many issues like this, and collecting more spec-tra may exclude (or reveal) large RV variations from aneclipsing binary scenario.
Second, a search for secondary eclipses at all phasesshould be performed to exclude a scenario with a highlyeccentric binary. The search method used here was themodel-shift uniqueness test designed by Coughlin et al.(2016). This method compared off-transit portions ofthe light curve with the transit portion of the best-fittransit model (and the transit model inverted, to providea visual comparison of detection significance). An evenmore rigorous method would consider secondary eclipsesof duration and depth distinct from that of the transit.
Third, when validating exoplanets using vespa oneshould be very careful about which broadband photom-etry is used and what offsets and systematics there are.Statistical validation work on data from the original Ke-pler mission took advantage of high-quality and uniformbroadband photometry from the Kepler Input Catalog(KIC, Brown et al. 2011). The analogous EPIC cata-log for K2 is similarly vital to the analysis of the K2star and planet sample. However, it is approximatelyfour times larger and was produced by collecting archivalphotometric measurements; therefore, it is more hetero-geneous and more prone to systematic errors and offsetsthan the KIC. We have found that in some cases, thesesystematic errors or offsets in photometry can result inuntrustworthy FPP estimates, in particular, extremelylow FPP measurements for known or likely false posi-tives. For example, when we input to vespa all availablebroadband photometry from the EPIC catalog for thecandidate EPIC 211418290.01, vespa yielded an FPPlower than 10−6 because it was unable to find an accept-able fit to a binary star model due to underestimatedphotometric uncertainties and therefore incorrectly ruledthis false-positive scenario out. However, inputting only2MASS photometry to vespa yielded a better fit to theeclipsing binary scenario, and vespa therefore returned amuch higher FPP of about 0.6. Situations like this were
not uncommon, which is why we ultimately decided touse only photometry from the all sky 2MASS survey. Wechose to use only the 2MASS survey because it providesbroadband photometry for all of our candidates and op-erates in the infrared, reducing the effects of reddening.Including photometry from additional surveys that arecalibrated differently and have distinct systematic un-certainties would introduce non-uniformities that wouldbe difficult to quantify and could bias our results.
To be conservative, we also added 0.02 mag of system-atic error in quadrature with the reported error for each2MASS band we used. This will continue to be impor-tant after the launch of TESS, which will observe targetsselected from the TESS Input Catalog (TIC, Stassunet al. 2017). The TIC will be very important for select-ing candidates for observation and follow-up; however, itis being assembled in a manner similar to the EPIC andis approximately 10 times larger, so it may have similaror even greater photometric offsets.
Fourth, it is very important to make and remake acandidate’s light curve with multiple apertures of vary-ing sizes, in order to determine whether the transit signaloriginates from the target star or a nearby backgroundstar (and thus exclude background false-positive scenar-ios). This test caught many false positives in our ownanalysis, and has been used successfully before in othercandidacy analyses (e.g. Dressing et al. 2017b).
Fifth, transiting giant planets are nearly indistinguish-able from eclipsing brown dwarfs or small M-dwarf stars,since they have roughly equal radii. Great care shouldbe taken when interpreting the output of vespa for gi-ant planets, and unless there is a clear way to distin-guish between the two scenarios (via RV measurements,secondary eclipse detection, composite spectra, etc.), at-tempts to validate large planets can be difficult and proneto error.
By considering each of the above lessons and incorpo-rating them into future validation analyses, misclassifi-cations of validated planets can be significantly reducedand hopefully eliminated in all but the most perversescenarios.
We will now investigate some of the individual vali-dated planets in our sample as well as the characteristicsof our sample as a whole.
7.2. A New Brightest Host Star in the K2 and KeplerPlanet Samples
One interesting target in our sample is EPIC205904628 (HIP 110758, HD 212657), an F7 star ob-served in Campaign 3. We detected and validated a2.8 R⊕ planet on a 10-day orbit. At a V magnitudeof 8.24, EPIC 205904628 is now the brightest star atoptical wavelengths in the entire Kepler and K2 sam-ples to host a validated planet. EPIC 205904628 is justslightly brighter than Kepler-21 (V = 8.25), a star ofsimilar spectral type found during the original Keplermission to host a single short-period exoplanet (Howellet al. 2012; Lopez-Morales et al. 2016). TESS is ex-pected to discover planets around many stars this brightand brighter.
We note that due to its brightness, we applied somespecial care to this star. In particular, we re-reducedthe K2 light curve by extracting light curves from largerphotometric apertures than our standard pipeline uses.
New Candidates and Planets Transiting Bright Stars 17
We also incorporated information from 2MASS J-bandimaging to rule out additional stars in the photometricaperture by calculating a contrast curve and inputting itto vespa to provide deeper imaging constraints than ourspeckle image.
7.3. Characteristics of the Sample
In addition to individual planets in our sample, it isinteresting to explore a few of the demographics of thenewly validated exoplanet population. Figs. 8-15 revealvarious aspects of the validated exoplanet sample andthe exoplanet candidate sample.
7.3.1. The Stellar Magnitude Distribution
Fig. 8 is a histogram of the distribution of bright-nesses for the host stars in our sample compared withthe brightness for stars hosting known Kepler planets(downloaded from https://exofop.ipac.caltech.edu/; ac-cessed 2017 December 4). Most of the candidates in ourpopulation are clustered near stellar magnitudes of Kp
= 12 to Kp = 13, and the cutoff we imposed at Kp =13 is very evident. Fig. 8 also shows the distributionof brightnesses for host stars to known Kepler planets.This distribution peaks near Kp = 15 and drops rapidlyat brighter magnitudes. It is more difficult to find planetcandidates around faint targets for K2 than for Keplersince the baseline is shorter. Therefore K2 candidatestend to orbit very bright host stars relative to Keplercandidates, making K2 candidates excellent targets forfollow-up observations.
7.3.2. The Effective Temperature Distribution
Most of the validated planets and candidates we iden-tified orbit host stars with effective temperatures in the5000 − 6000 K range. However, out of 233 stars inour sample 41 are cooler than 5000 K and 25 are hot-ter than 6000 K. No stars in our sample are coolerthan 4250 K or hotter than 6500 K. See Fig. 9 for acomparison with the Kepler sample (downloaded fromhttps://exofop.ipac.caltech.edu/; accessed 2017 Decem-ber 4).
7.3.3. The Period Distribution
We also explored the period distribution of our candi-date population. As can be seen in Fig. 10, the typicalvalidated planet or candidate has an orbital period of 20days or less. This should come as no surprise, given thebaseline of ∼75 days of K2 observations per campaignfield. Of 275 candidates in our sample, only 46 haveperiods longer than 20 days, and only 10 have periodslonger than 40 days.
7.3.4. The Multiplicity Distribution
Most of the candidates in our sample (validated or oth-erwise) are the only candidate in their system to havebeen detected. However, our sample does include 21 sys-tems with two candidates (15 of these have only vali-dated planets), 9 systems with three candidates (8 ofthose have only validated planets), and 1 system withfour candidates (EPIC 212157262; all candidates in thissystem are validated). The full multiplicity distributioncan be seen in Fig. 11.

Figure 8. Histograms of the Kepler magnitude for host stars tovalidated planets (purple) and candidate planets (diagonal lines)from C0-C10 of K2 that have been identified in this work, as wellas a comparison with host stars to confirmed Kepler planets (pink).There is a fairly sharp cutoff in our sample near magnitude 13, sincevalidation was only conducted on stars for which we had a spectrumand almost all of the spectra we used were for targets brighter than13th mag. The typical Kepler host star is much fainter, with thepeak of the distribution near 15th mag, which makes K2 targetstars much more suitable for follow-up observations than Keplerstars. Moreover, the brightest star hosting a validated planet inour sample is EPIC 205904628, a V = 8.2 star with a 2.8 R⊕ planeton a 10-day orbit. Validated in this work, EPIC 205904628 is nowthe brightest host star for a validated planet in either the Kepleror K2 samples.
7.3.5. The Planet Radius Distribution
One of the more interesting features of our sample wasthe radius distribution. Fig. 12 demonstrates the fullplanetary radius distribution of our sample for both val-idated planets and candidates. As expected, there is asharp cutoff in planet radius for validated planets at Rp
= 8 R⊕ (since we generally chose not to validate largerplanets).
In order to investigate the radius distribution of theunderlying planet population, we adopted and applied arough completeness correction to our planet sample. Wedetermined the completeness of our K2 planet detectionpipeline by performing injection/recovery tests. We in-jected planet signals into K2 light curves over a range ofexpected S/Ns (analogous to the injection/recovery testsperformed by Petigura et al. 2013; Dressing & Char-bonneau 2015; Christiansen et al. 2016 on the Keplerpipeline). We then calculated for each of our planet can-didates the number of stars observed by K2 around whichwe could have detected the candidate, and weighted thecontribution of each candidate to the histograms by thatfactor and the geometric transit probability.
The uncorrected and corrected distributions for vali-dated planets and candidates can be seen in Fig. 13, whilea comparison of our corrected candidate sample to theFulton et al. (2017) sample and a log-uniform distribu-tion can be seen in Fig. 14. Additionally, a completeness-

By visual inspection of these figures alone, our cor-rected candidate sample appears to exhibit a gap in theradius frequency around 1.8− 2.0 R⊕, similar to the gapin the Kepler planet sample explored by Fulton et al.(2017). They argued that the underlying astrophysicaleffect could be photoevaporation, whereby stellar inci-dent flux strips a planet’s H/He atmosphere if the at-mosphere is not thick enough, leaving a population ofstripped, rocky planets and an untouched population oflarger, gaseous mini-Neptunes (Owen & Wu 2013; Lopez& Rice 2016; Owen & Wu 2017; Van Eylen et al. 2017).As an alternative hypothesis, they also suggested thatgas accretion could be delayed during planet formationuntil the protoplanetary disk is already gas poor, creat-ing a population of small, rocky planets (Lee et al. 2014;Lee & Chiang 2016).
We wished to analyze in a more quantitative fash-ion how the completeness-corrected radius distributionof our K2 candidates compared to the completeness-corrected Kepler candidates from Fulton et al. (2017);we decided to also compare against a log-uniform distri-bution to probe the significance of a possible bimodality(as did Fulton et al. 2017). We binned all three nor-malized distributions in 0.1 R⊕ intervals from 1.2 to 2.5R⊕. We assigned error bars to our own sample and theFulton et al. (2017) sample via Poisson statistics (forthe number of candidates in each bin) and then scaledthe uncertainty according to the completeness-correctionscaling applied to each bin.
We then calculated χ2reduced between our sample and
that of Fulton et al. (2017) as well as our sample andthe log-uniform distribution, finding values of 2.21 and2.34, respectively. Across all bin numbers from 5 to 20for which there were more than two candidates in every

(equally sized and spaced) bin for all samples, the av-erage χ2
reduced was 2.21 between our sample and that ofFulton et al. (2017) and 2.95 between our sample and thelog-uniform distribution. However, we note that a largeportion of the χ2
reduced between our sample and that ofFulton et al. (2017) is caused by only the smallest radiusbin. Still, the Fulton et al. (2017) sample did not pro-vide a significant improvement in goodness of fit than asimple log-uniform distribution. This suggests that thevisual gap in our candidate sample cannot be quantita-tively confirmed unless future observations and planetdetections are made to increase the sample size.
7.3.6. Future Applications
The K2 mission has thus far conducted observationsthrough more than 15 campaigns, and it will continueobservations for future campaigns until it expends all ofits fuel. Given that the validation infrastructure built forthis research is directly applicable to future campaigns,we will be able to identify and validate exoplanet candi-dates from upcoming campaigns as quickly as the neces-sary follow-up observations can be collected.
This research will also be useful even after the end ofthe K2 mission. The upcoming TESS mission (Rickeret al. 2015) is expected to yield more than 1500 total ex-oplanet discoveries, but it is also estimated that TESSwill detect over 1000 false-positive signals (Sullivan et al.2015). Even so, one (out of three) of the level-one base-line science requirements for TESS is to measure themasses of 50 planets with Rp < 4 R⊕. Therefore, anextensive follow-up program to the primary photomet-ric observations conducted by the spacecraft is required,including careful statistical validation to aid in the selec-tion of follow-up targets. The work presented here willbe extremely useful in that follow-up program, since onlymodest adjustments will allow for the validation of planetcandidate systems identified by TESS rather than K2.
8. SUMMARY AND CONCLUSIONS
In this paper, we processed 208, 423 targets from C0-C10, removed instrumental systematics from the K2 pho-tometry, and searched for TCEs. We identified ∼30, 000TCEs, which were subjected to triage and vetting. Ofthese, ∼1, 000 target systems passed both procedures andwere upgraded to candidates. Of these, 275 candidates in233 systems had at least one usable TRES spectrum. Foreach candidate, we also collected and analyzed follow-upobservations, including spectroscopy and high-contrastimaging. We derived transit/orbital parameters fromthe K2 photometry, stellar parameters from the spec-tra, and contrast curves from the high-contrast imaging.Then, using these results, we determined the FPP of eachplanet candidate using the vespa validation procedure(Morton 2012, 2015b), which calculates the likelihood ofvarious false-positive scenarios as well as the true-positivescenario. These FPP values were then adjusted appro-priately for systems with radial velocity measurementsand for multiplanet systems (see Section 5.1). We re-ported the resulting FPPs for our planet candidates (seeTable 4) and classified candidates with FPP < 0.001 asvalidated planets.
Of the 275 candidates, 149 had an FPP below thevalidation threshold of 0.001, while 126 remained candi-dates (FPP > 0.001). According to the NASA Exoplanet
Archive35 and the Mikulski Archive for Space Tele-scopes36 (both accessed 2018 February 14), of the 149newly validated exoplanets, 56 have not been previouslydetected, 39 have already been identified as candidates,53 have already been validated, and 1 has previouslybeen classified as a false positive (EPIC 210894022.01;see Section 6.2). As a result, this work will increase thevalidated K2 planet sample by nearly 50% (and increasethe K2 candidate sample by ∼20%. The full dispositionresults can be found in Table 2.
Most of the newly validated exoplanets orbited hoststars with 12 < Kp < 13 and 5000 K < Teff < 6000K. Additionally, the majority of validated planets hadorbital periods < 20 days and planetary radii between 1and 4 R⊕. Our complete candidate sample also showssigns of a frequency gap in the radius distribution (seeFig 14), similar to the gap found by Fulton et al. (2017).However, further analysis with a larger planet sample isrequired to confirm the radius gap for K2 planets.
This work has clear broader implications. The abil-ity to validate planet candidates is vital to conductinga successful follow-up and confirmation program. Thewide applicability of the validation infrastructure devel-oped in this research is clear from the large number ofcandidates subjected to our validation process. By con-tinuing to apply the validation process described here,future K2 campaigns and the upcoming TESS missionwill benefit from a valuable source of validated planetsand a useful validation pipeline able to process the largeand constant supply of identified planet candidates.

APPENDIX
CALIBRATING TRES TO MEASURE THE MT. WILSONSHK INDEX
Our work involved the analysis of many spectra col-lected with TRES on the 1.5 m Tillinghast telescope atthe Whipple Observatory on Mt. Hopkins. In additionto using TRES spectra to derive spectroscopic parame-ters and measure radial velocities, we also used TRES tomeasure the Mt. Wilson SHK activity indicator. SHK
is a ratio between the flux in the cores of the calciumII H and K spectral features (at 3933.66 ± 1.09 and3968.47± 1.09 A) and the flux in two nearby continuumregions (one slightly redward of the Ca II lines calledR, and one slightly blueward called V ). SHK is com-monly used as a proxy for a star’s chromospheric activ-ity (Isaacson & Fischer 2010). Because SHK depends onratios of fluxes at different wavelengths, it is sensitivelyaffected by the spectrograph blaze function. The effect ofthe spectrograph blaze function must therefore be care-fully calibrated and quantified in order to standardizemeasurements of SHK from different instruments. Inthis appendix, we describe how we calibrated the TRESspectrograph to place measurements of SHK on the Mt.Wilson scale, and present our measurements of SHK for ahandful of bright K2 planet candidate hosts for which wewere able to measure SHK reliably. These measurementsare listed in Table 3.
To calibrate TRES to measure SHK on the Mt. Wilsonscale, we closely followed the procedure of Isaacson &
Fischer (2010). We based our calibration on a sample ofstars that were both observed by TRES (prior to 2016June 1) and were included in the Duncan et al. (1991)catalog of Mt. Wilson SHK measurements. Additionally,the following cuts were applied to improve the samplequality:
1. TRES spectra for the star in question were onlyused if the photon count in the R continuum region(4001.07 ± 10 A) was greater than 174,000. (Thecutoff is actually at 150,000 ADU, which is con-verted using a gain of 1.16 for TRES.) This conser-vative cutoff was imposed to remove spectra withonly low or moderate S/N from the calibration.
2. The star was not in a close binary or multiple sys-tem. We only included widely separated (& 5′′)visual binaries in order to prevent flux from thecompanion star(s) being blended with flux of theintended target.
3. One fast-rotating star (HD 30780, or ‘VB123’ inthe TRES database) was removed from the cali-bration set as the H and K emission cores wereclearly broadened and smeared with other spectralfeatures (v sin i ' 180 km s−1).
After these cuts, our calibration sample included 118stars with a total of 1204 individual TRES observations.The calibration was made in the same way as in Isaac-son & Fischer (2010), by determining values of Kcoeff ,Vcoeff , m, and b that minimize the differences betweenthe Mt. Wilson survey measurement of SHK for eachstar (Duncan et al. 1991) and SHK calculated from theTRES spectra using the following equation:
SHK,TRES = m× H +KcoeffK
R+ VcoeffV+ b (A1)
where H and K are fluxes in the cores of the Ca II H andK lines,37 R and V are continuum fluxes 38, Kcoeff is acoefficient that scales the magnitude of K fluxes to matchthe magnitude of H fluxes, Vcoeff is a coefficient thatscales the magnitude of V fluxes to match the magnitudeof R fluxes, and m and b are free parameters.Kcoeff was calculated through a linear regression be-
tween H and K for our TRES spectra, so as to scale themagnitude of K to match that of H. The same processwas performed for R and V in order to calculate Vcoeff .This was done to mirror the approach taken by Isaacson& Fischer (2010) in their calibration of the Keck HIRESinstrument.
We estimated m and b by minimizing the differencesbetween SHK,Mt.Wilson from the Mt. Wilson survey(Duncan et al. 1991) and SHK,TRES determined fromTRES spectra with Equation A1 using an MCMC algo-rithm with affine-invariant ensemble sampling (Foreman-Mackey et al. 2013). We calculated the likelihood, L,using the following function:
37 The H and K fluxes were calculated by integrating the spec-trum over triangular-shaped bandpasses centered at 3933.66 and3968.47 A, respectively, each with a FWHM of 1.09 A.
38 The R and V fluxes were calculated by integrating the spec-trum over 20 A wide box-shaped bandpasses centered at 4001.07and 3901.07 A, respectively, following Duncan et al. (1991).

where σ is a jitter term that absorbs uncertainties in bothin measurements of SHK and in their uncertainties dueto factors including astrophysical variability in the SHK
index of a single star over time. We imposed uniformpriors on m and b, and imposed a Jeffreys prior on σ.
It is important to note that there might be both mul-tiple TRES spectra and multiple Mt. Wilson SHK mea-surements for a given star. So if a star had more than oneTRES spectrum or Mt. Wilson SHK measurement, thisstar was simply represented as a grid of TRES and Mt.Wilson measurements in the MCMC process. With thisin mind, the total number of data points in the fittingprocess was 3108. This implicitly gives higher weight inour calibration to stars with multiple observations, whichhelps average out astrophysical variability in SHK .
Our MCMC process used 200 chains of 50,000 stepseach in order to explore parameter space and determinebest-fit parameters and uncertainties. The resulting en-semble was well converged according to the Gelman-Rubin statistic (Gelman & Rubin 1992), which in thiscase was lower than 1.04 for all parameters. The last 500samples of the MCMC process are visualized in Figure16 with a posterior corner plot (Foreman-Mackey 2016).We found the following parameter values from our modelfit:
Kcoeff = 0.876
Vcoeff = 0.775
m = 15.496+0.068−0.069
b = −0.0031± 0.0015
ln(jitter) = −3.119± 0.013
There was also significant covariance between m andb (see Fig. 16), which we estimated to be Cov(m, b) =−8.571× 10−5.
Statistical uncertainties, σrandom, for SHK were calcu-lated by propagating sample draws from four Poisson dis-tributions representing R, V , H, and K through drawsfrom the m and b posterior distributions and the Kcoeff
and Vcoeff values. We also included a systematic errorterm, σsystematic, in our uncertainty estimates. We esti-mated the systematic uncertainties for TRES SHK mea-surements using six spectra with high S/N of the brightstar Tau Ceti collected with TRES on the night of 2013October 24. We assumed that SHK for Tau Ceti re-mained constant over the course of a single night, andestimated a systematic error term based on the scatterbetween individual SHK measurements. Our final errorestimates, σtotal came from assuming that the statisticaluncertainties and systematic uncertainties were indepen-dent and could be added in quadrature as follows:
σ2total = σ2
systematic + σ2random (A3)
We note that our calibration for SHK is only validover specific ranges in parameter values. Our calibrationwas performed over a range of 0.244− 1.629 in B-V and

yielded SHK values ranging from 0.055 to 2.070. Basedon tests with simulated data and with real data with lowS/N, we are cautious of SHK measurements on spectrawith fewer than 290,000 photon counts (or 250,000 ADU)in the R and V continuum regions combined. We alsonote that SHK measurements can be affected by rapidstellar rotation. We found by artificially broadening thelines of slowly rotating stars that SHK measurementsfor stars with v sin i above 20 km s−1 can be skewedcompared to the values that would have been measuredif the stars were rotating slowly.
We tested our calibration by comparing SHK measure-ments derived from TRES with a test set of SHK mea-surements from the literature (in particular, we focusedon stars observed by Isaacson & Fischer 2010). We con-structed the test data set by identifying stars observedby TRES with the following properties:
1. The stars were not included in our calibration set(stars observed both by Duncan et al. (1991) andTRES).
2. The TRES spectra for the star in question havephoton counts in the R continuum region greaterthan 174,000 (or 150,000 ADU).
3. The star had at least one SHK measurement fromKeck HIRES that had been reported in Isaacson &Fischer (2010).
After applying these cuts, we were left with a test setof 121 stars, which had been observed a total of 4308times by TRES.
We show the results of our SHK calibration in Figure17, which compares TRES SHK measurements from ourcalibration set with measurements from the Mt. Wilsonsurvey, and in Figure 18, which compares TRES SHK
measurements from our test set with values from Isaacson& Fischer (2010).

Figure 18. Comparison of our SHK calibration for TRES withthe Isaacson & Fischer (2010) catalog for our test data set of 121stars (with 4308 TRES spectra). Each red point denotes a uniquepair of observations from TRES and Mt. Wilson for a given star.The fractional RMS scatter on the calibration set is 13.6%.
For the calibration set, there is an 10.9% fractionalRMS scatter about the one-to-one line. The only no-ticeable outlier appears to be at approximately (0.9,0.2),corresponding to the single TRES spectrum (and Mt.Wilson measurement) of HD 120477, a variable star ob-served in 2015 July by TRES and observed no later than1991 at Mt. Wilson. The reason for this outlier could notbe identified, but its presence in the calibration set didnot significantly change the calibration, so it was left in(removing the point maintained a fractional RMS scatterof 10.9%.)
As for the test set, there is a 13.6% fractional RMSscatter about the one-to-one line, slightly larger than forthe calibration set (which is to be expected). There doesappear to a slight systematic offset between TRES andKeck HIRES such that SHK values from Keck HIREStend to be lower than those from TRES. However, thisis to be expected, since the same systematic underesti-mation with Keck HIRES compared to Mt. Wilson canbe seen in Fig. 4 of Isaacson & Fischer (2010). There arealso a few obviously errant data points in this figure, cen-
tered around (1.5, 0.5). These data points correspond tofour TRES spectra of the star GJ 570B, a spectroscopicbinary. The test data set, because it was not used forcalibration, was not clipped of binary stars; thus, GJ570B is a clear example of how calculating SHK for closebinaries can go wrong. However, the presence of thosefour spectra has very little effect on the results; removingthem only reduced the fractional RMS scatter of the testset to 13.5%.
