I looked up the I-band information. Most candidates fall into one of the
3 cathegories:
a) clear signal, b) no signal or fluctuation, c) there is a CR in that
place. Could not really
conclude anything about candidates # 0 and 1. They are on subtractions
|acs04maysub-i/norm01i,
|for which the "new" images looks exactly the same as the subtraction in
the tiles.
The "global" images for the new and the subtraction are very similar as
well, with
the subtraction showing slightly less flux than the new. It seems that
the reference
image calibration is off (scaled down). Therefore I cannot trust the
information for
these candidate.
