Before diving into any reviews I would point out that there are two test failures that are likely related as I don't see them on main (though I haven't looked into the details).

They are "remote" tests, so CI doesn't pick them up, run them with pytest -P esasky -R

For me they are failing both on this branch and on main. Both failing tests are for the IUE mission, and they are the only tests for that mission. The first test that fails are failing because the request is timing out when trying to fetch the fits file http://sdc.cab.inta-csic.es/ines/jsp/SingleDownload.jsp?filename=LWR13178RL.FITS. I was sort of hoping that this was some temporary problem with the server hosting the IUE data, but since it has been failing for many days now, maybe it's worth investigating some more.

I have contacted the IUE support team regarding the timeouts, but these issues seem unrelated to this particular PR.
