When you go into imview to look at the magnitudes on the invidual
images, the magnitudes you get are TOO HIGH (i.e. too dim) by 0.75
magnitudes, due to a bug in the processing. Please take this into
account. (imview still is fine for consistency checks.)
Note also that the magnitudes in imview are for the host+the supernova,
so in general (when the magnitudes are right) you will see *lower*
(brighter) magnitudes in imview for the individual images than you see
in the subtraction. The bug offsets this (and will fortuitously offset
it just the right amount if %INC is 100), but it wasn't intentional!
