The files n6791*.jk were provided by Ken Janes.  "ctr" applies to the
cluster, "e, n, s, w" refer to comparison fields roughly 18 arcmin from
the cluster in the four cardinal directions.  Cross-IDs from n6791ctr.jk
are included in NGC6791.xid (matchup tolerance = 1 arcsec); note that
n6791*.jk contain multiple entries for some stars.
montgomery.dat was retrieved from J.-C. Mermilliod's web site.

The directory Variable_stars contains individual-epoch magnitudes for
stars identified as likely variables.

The data table from Kaluzny 1990 contains several duplicate entries:
two entries in the table with (x,y) coordinates within 0.5 pixels
from each other, and similar magnitudes and colors.  In kaluzny90.pruned
seven of these pairs have been replaced with seven individual entries
at the unweighted mean position, magnitude, and color.
