User interface and infrastructure (& utilities)
From Jim: "*gtmktime* \ [future name for *gtmaketime*] has been optimized and showed a factor of 50 speedup for a 10^7 s *gtobssim* simulation with standard orbit and rocking. *gtmktime* does not modify TSTART or TSTOP or other date keywords. Wiki Markup
gtselect can now accept a list of FT1 files. Non-GTI keywords are compared for consistency, but GTIs are not examined, so one can have overlapping GTIs (and potentially multiply-included events); and the GTIs are merged without discretion. gtselect ensures that the TSTART, TSTOP, and date-related keywords are synched up to the user's
selections in all HDUs."
The above modifications mean that the GTI bounds will not necessarily correspond to the TSTART & TSTOP values.
Source Catalog
Met this week. Jean reported that a preliminary catalog for obssim2 is ready - ancillary information like light curves and fluxes in different bands will come later but the numbers of sources should not change. He has provided it to Tom for posting at the GSSC and will make an announcement in the SC Users Forum when it is ready. the catalog analysis relied on binned likelihood and so was not affected by the swap of front and back HANDOFF response functions.
