Flats & noise propagation; who's up for an experiment?

[admin]

Thank you Simon. Downloaded and put in the "test sets" folder!
I was looking at making some sort of composite from the "good" stacks, but they don't appear to be aligned against each other...

Oh, my apologies. I am using different stacking software (DSS was having horrible trouble with my calibration frames). So I moved to ASTAP a few days ago, and it's superb. One of the only real problems with it is that it didn't align frames for composition -- it can merge three separate frames into a single RGB FITS, but that's not useful for StarTools. I say it "didn't" because two days ago I explained this to the developer, and yesterday he produced a version which can now align frames

I'll run them through the alignment routine and re-upload.

Ok, aligned 'good' frames are here:
