emevents (emevents-8.8) [xmmsas_20230412_1735-21.0.0]

Comments

• The reanalysis of events in EV_REC, CUT_BAD and BINODAL calls a C routine (edusoft) which interfaces to the C routine (edu_simu, written by M. Lortholary of the EPIC/Saclay team) which simulates the EDU recognition.
• The search for new bad pixels in the data should be performed after emevents so that known bad pixels are removed and positions are correct.
• Instead of zeroeing bad pixels in CUT_BAD, it may be possible to subtract their average level (usually well defined), leaving only increased noise.
• In 2-node operation, the task must be run twice (once for each node). Thus the projection of events back to the CCD map in BINODAL is done twice. This is not expected to be a big overhead. The alternative would be to generate both output event lists in the same task.
