Greg noticed a systematic offset in the zeropoints in the I-band
images. These are typically 0.2 magnitudes, but some are very
different.

Taken into account BOTH Of my screw-ups (one of which I don't know the
reason for, only that I made it), below are the corrections that need to
be applied to all candidates.

The Z is the same as before for everything but tilt16 (those zeropoitns
were fine), but I has been changed.
