Karen,

Yes, I noticed the 'minimal" header that is created when writing the combined image to disk.  I think it was 6 lines long ;-)

I'm no expert, but I have a sense of what should be preserved.  As mentioned, I am currently using ASTAP which seems to handle this correctly.  I know you've worked with Han (the author) before and he could probably help here.

I can provide you with the header of an unstacked image and the new header after stacking.  By comparing them you could get a sense of what should be preserved.

I *might* be able to help with this since I'm the one requesting it.
