Groups of Galaxies. III. The CfA Survey

Groups in the catalog are all density enhancements in redshift space of a factor greater than 20. All groups contain at least three members.

There are 176 groups in the catalog and 102 groups have been identified in one or more previous studies. The catalog includes group numbers, numbers of members, equatorial coordinates, mean flow-corrected galactocentric velocities, line-of-sight-velocity dispersion, integrated group magnitudes, crossing times for the groups, and mean harmonic radii of the groups.
