Thank you very much @jacob-hjortlund ! (I am currently a bit slow due to a newborn).
I have one minor request.
The CI failed due to something unrelated that is not as stable (did not find a halo in the sky area). If you re-trigger the test, chances are that it passes (and need to be made more stable, but not your issue).

[sibirrer]

can you describe what tests are being executed here and why? It is just unclear to me but might be helpful

[jacob-hjortlund]

Sorry, this test was added after my first push. The point was to see if only this test was run, or if everything was rerun, i.e. actually checking if testmon is doing what is should. It'll be removed later in this PR.

Thanks, I thought that was the case. I was planning on seeing if I could fix a seed to remove the flakiness of the test, but have been busy with some travel + #365. Hope everything is going well with the newborn! 😄
