    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.
