DavidT3 / XGA

X-ray: Generate and Analyse is a module designed to make the analysis of XMM observations simple and efficient. It provides an interface with SAS for the creation of XMM data products, as well as a way to easily perform fits (scalable for multiple observations) and retrieve information about an object, all within a Python package.

Some eRASS observations might not have data from all TMs #1157

When the erosita cameras are hit by a cosmic ray, the cameras need to be reset, so there is 12 hours where they are turned off. See the link for more details: https://erosita.mpe.mpg.de/dr1/eROSITA_issues_dr1/camera_resets_dr1.html

Would be worth checking if this has resulted in any skytiles that have missing instruments, and how we would ingest that information into XGA, as currently all the telescope modules are assigned to every obs.

We should probably check to be sure as you say, but I suspect that is probably not an issue - even the eRASS:1 data are made up of multiple bursts of observation for each skytile separated by a few hours (p.s. I'm trying out replying to this issue from slack, so no idea how this will come through on GitHub)
