    Here's a faster way to do it.

    Use the simplehstltcv software to make ACS lightcurves.

    Find the appropriate position on the Subaru images (new and old of which
    will be loaded into the database as I finish with them tonight), and
    plop down apertures by hand, once on the recent, once on the old Subaru
    images. Subtract the photometry. (You can do a transformation from the
    ACS images if you want accurate positions.) (Imview supports plopping
    down apertures by hand now; that's what Vitaily was using earlier to
    look at individual images.)

    At that point, you've got your lightcurve, and the procedure is less
    involved than running Ivanlight would be.
