It is not a data reject process in CCD stack2, its a resample after align, so it makes sence it would make a difference in resizing. The samples I posted were all bin 1, perhaps it would make more of a diff with a mix of bin1-bin2 subs.

The thing that worries me about the nearest neighbor is the way it distorts the image. But every time I try it, it seems to work well.
