list.dat          - list of variable stars with their parameters

remarks.txt       - remarks on selected objects

phot/I/           - I-band photometry of individual objects
phot/V/           - V-band photometry of individual objects
phot.tar.gz       - gzipped phot/ directory

fcharts/          - finding charts of individual objects

Finding charts are gzipped PostScript images. These are 60"x60" subframes
of the I-band reference frames centered on the star. White cross marks the
star. North is up and East to the left.
