Are the coords for pre-existing candidates calculated differently (and therefore correctly)?

    Hi Rob,
        When we were hunting for the correct coordinate for #049, at one
    point we tried going to "pre-existing candidate" tiles while looking at
    the original search. Surprisingly a pre-existing candidate tile came up
    listing exactly the *correct* GOODS Ra&Dec coordinates AND the correct
    pixel x&y coords (as opposed to the incorrect RA&Dec coords with which
    #049 was saved) -- and of course it didn't know that it was near #049.
    We saved this as #174, for the record. So the question is: Is it
    possible that the RA&Dec coords are calculated differently (and
    correctly) for the *pre-existing* candidates based on the pixel x&y
    coords, even when they were calculated incorrectly the first time the
    candidate was found?

    If so, this might be a much easier way for us to find the correct coords
    for candidates that got wrong RA&Dec's last night -- although I doubt
    there will be more to do of those.
