Hi!
I wondered if there was any way to zero the non-DR1 parts of the exposure maps of skytiles along the DE-IKI divide when generating them?
XGA (https://github.com/DavidT3/XGA) uses exposure maps to judge how much of a user specified source region is covered by a particular telescope, and unfortunately with the eRASS exposure maps we generate at the moment that can lead to some false positives - is there any way to force the exposure map generation to zero out the part of the tile we don't have events for?
Cheers,
David

Hi David,
Unfortunately, there is no such option on the eSASS4DR1. You could use Python to cut the exposure maps using these boundaries:
sel_de = (g_l > 179.94423568) & (g_l <= 359.94423568)
This will be corrected in future eSASS releases.
Best wishes,
Miriam Ramos-Ceja

Hi Miriam,
That is a very good point, thanks very for a good stop-gap solution!
