Description:
  The catalog is a list of 100 compact groups of galaxies identified
  by a systematic search of the Palomar Observatory Sky Survey red
  prints.  Each group contains four or more galaxies, has an estimated
  mean surface brightness brighter than 26.0 magnitude per arcsec and
  satisfies an isolation criterion.  The catalog includes running
  numbers, equatorial coordinates, group types according to the two
  brightest members, number of galaxies in the group, angular
  diameters of the smallest circles containing the geometric centers
  of all group members, total magnitudes (red) of those galaxies
  counted as group members, estimated red magnitudes of the brightest
  galaxies in the groups, corrected redshifts of the brightest
  galaxies, and other designations of the groups.
