Is there a paper we may now reference that elucidates these data?

Am I right in assuming that images were taken at the UH 2.2m unless otherwise 
indicated?

What are RA_OFF and DEC_OFF?

Pixel types vary (2-byte integers, 4-byte integers and reals).  Is this a
problem?

Max and min are not given consistently.  Should we derive these and add them
to all PDS labels?

Photometry is provided only for three nights, and the notes supplied with 
the photometry indicate that the other data are in different stages of
reduction.  This strikes me as a problem.  The images should at least all
be at the same stage of reduction, yes?

What about the coordinate epoch: is "1950" really "B1950" and "2000" "J2000"?
If not, what are they?  And what does an epoch of "2000.5" mean?
