Ok, I looked at the example for acs04d-137 in Rob's note, and I looked at
the subtraction. From this I conclude that imview has placed the aperture
below the the correct location, and that the source detected by the
subtraction is due to 2 CR's which are apparent at the left edge of the
central galaxy on 137-indiv3 and 137-indiv4. This resulted in the
erroneous conclusion that only one CR caused the detection.
Do you agree Rob?
