Tech Note 102: the Mark IV "patch" dataset (updated)

[Michael Richmond <richmond@stupendous.cis.rit.edu>]

  I have updated my draft of TN 102 to include a description
of my attempt to calibrate the photometry against Landolt
stars.  See it at

      http://stupendous.rit.edu/tass/technotes/tn0102.html

  I welcome comments and suggestions.  There is still a bit of work
to do before I declare this TN complete.
