CURRENT UNDER STUDY

Flaring background filtering per source


bkgoptrate

Flaring background filtering for source detection assumes errors are dominated by background

… not the case for sources bright enough to extract a spectrum

EPIC RMF in PPS/XSA


Canned response matrices: Files: PN: 270 files (3 epochs, 6 modes, 3 patterns, 10 RAWY) M1/2: 168 files (14 epochs, 2 modes, 2 patterns, 3 regions) Size: PN: ~4MB M1/2: ~13MB ~ 30MB per source PPS products:

• ~130MB per ObsId • ~10 sources with spectral products per ObsId • ~300MB in RMF per Obsid

XSA:

• 130k sources with spectra => ~4TB only for EPIC RMF

RMF for RGS 2nd order / RGS lightcurve timebin


• ~10MB per 2nd order RMF/ARF

• ~ 12k observations

120GB in XSA

Current RGS light curves are created with a fixed time bin of 1000s

Select time bin in the range 100-1000s according to mean rate
