Hi @ArmelleJB !
Many thanks for this PR. I'll mark it as draft for the time being, as I understand it is not yet complete.
At some point, in your user script, could you provide an example on how to launch a flatfield computation please ?
Could you also please run pre-commit hooks and commit the linted code ?

Hi!

The PR #163 has been merged, which results in a couple of small conflicts in this one that I'll try to resolve.

Note that I had to rebase this branch from main, but a good point is that the CI/Lint job now passes !
