What my zapper will be is probably really cheating-- i.e. an image
processing program putting in something that "looks nice". It's easy,
though, and I think it's fine (as nobody's going to do anything
quantitative with these images anyway).
Automatic rejection is problematic as is, given the borderline sampling,
and given that one of the main real features of the image *does* vary
substantially between all the images I'm summing.... I played a little
with automatic rejection, and unsurprisingly the supernova suffered.
