     One simple method is to measure the magnitudes of a wide
range of stars visually, then compare those measurements against
photoelectric photometry and look for a systematic pattern in
the residuals.  You can find a set of fields with good photometry,
and then, say, make a set of charts in which you remove some of
the known magnitudes.  Use your eyes to measure those "unknown"
magnitudes, and do the comparison.

     I was involved briefly in a little spat which involved
the claim of a systematic error in a visual observer's measurements
of a SN as it aged and changed color.  You can find the last paper
in the controversy here:

      http://adsabs.harvard.edu/cgi-bin/nph-bib_query?
         bibcode=1996AJ....112..723J&db_key=AST&high=3f6510b0d811436

and work your backwards through the references, if you like.

     I am unable to post to VSNET, for some reason, so if you
think this reply might be of some general interest, you might
forward bits of it to the list.
