THIS IS PRELIMINARY
IF YOU APPLY ANY OF THESE FIXES TO MAGNITUDES ON WIKI PAGES, INDICATE
*CLEARLY* THAT YOU HAVE DONE SO.
The following magnitudes need to be ADDED to any candidate on the given
field.
These aperture corrections were generated by integrating a Tiny Tim
through the actual aperture used on each subtraction (it varied) and
comparing the result with the aperture correction of each subtraction.
If somebody wants to try to verify what I've done, I've tabulated the
aperture radii and (wrong) aperture corrections used in each subtraction
at the bottom of this message.
Somebody please sanity check these to show that they yield consistency
with what Adam's candidates were.
