19 Oct 2005 Chandra Users' Committee
Submitted Proposals
New in Cycle 7– Decrease in allowance for constrained observations:
15%, plus accurate accounting of # obsvns. – Database-based panel GUI software: faster and more
accurate access to proposal information– PDF files only– Electronic proposal distribution, hardcopies on request
(~20% requested hardcopy)– Spitzer joint time program– Fully-web-based peer-review reports– “War Room” at deadline time!

Grant Award Periods
Award Periods:– Grants may be requested for 1 or 2 years– One-year no-cost extension to allow completion of
science project is available on request with a brief justification
– Second one-year no-cost extension is also available if justified
Documentation:– CfP Section 8.6, updated to clarify – Updated Section VE of the Terms and Conditions ready
for Cycle 7: 1st extension straight-forward, 2nd or subsequent need justification

Constraints and the Peer Review
New Guidelines: – 15% of observations– Observation: individual pointing, e.g. count monitoring
sequence, or long observations split due to orbit– Each panel given quota determined by ratio of requested to
available constrained observations– Instructed to abide by the quota, but talk to me if they
needed/wished to go over
Results:– Real time determination of use/quota for each panel allowed
us to update quotas as needed– No panel turned down a highly ranked proposal due to this
quota

Suggestions from Panel Chairs Survey
Organization: generally very favorable comments Pundits: get involved in review reports in advance
of the review LP/VLP: panel chairs (or panels) should meet on
Wed pm to strategize on LP/VLPs Stop it being a race! Time: should we add another morning? Too may junior/non X-ray panel members:
– Starting much earlier to recruit panel chairs (5 already) and reviewers
– Strong emphasis on inviting only senior people first (it is much easier to get junior people!)

Revised Observation Completion Policy
Complete observation: 90% (or more) of allocated time has been observed
Exceptions, implemented 8 July 2005:– TOO/DDT due to scheduling restrictions– Observations >200 ksec, any remaining time > 20 ksec
will be observed Exceptions, proposed for 1 Dec 2005:
– Observations < 5ksec, observed only once– Observations with <2 ksec remaining will be
considered complete Policy posted on website and sent in an electronic
bulletin Will be described in Cycle 8 Call for Proposals

Summary of Response to Jan 2005 Report
E&PO:– Complexity of Process
> NASA requirements are inherently complex. They are holding workshops. The E&PO CfP will be updated to clarify.
– Low funding levels> 2% of GO budget: about $200K. No more funding is available,
unless CUC should recommend using more of GO budget to fund E&PO as opposed to GO science
All other items should have been covered during the day
