Thank you, Mike!

Your welcome, Sergio. Thank you for your data and comments, very helpful!

Right now I need a few sky flats and a matching bias. I want to double check that bright stars in the flats are discounted reasonably.

Thank you!

Here are script updates. Run them on mono frames, raw CFA frames, or channels extracted from de-Bayered CFA frames. See the tool tips for documentation.
