Description:
The catalog contains nearby groups of galaxies with outer number
density enhancement greater than 20. The groups were searched using a
whole sky catalog of 1312 galaxies brighter than mag 13.2 (B) with
complete redshift information (Huchra et al. =1983ApJS...52...89H).
Only groups containing more than two members are included.
The catalogue includes equatorial coordinates, average radial
velocities, and velocity dispersions for 92 nearby groups in the first
file. A second file contains the results of a comparison between this
catalog and de Vaucouleurs' (1975) catalog of nearby groups
The Hubble constant was assumed 100km/s/Mpc.
