cds-question@unistra.frgalaxy-clustersgalaxiescatalogsThe 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.1982ApJ...257..423Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/VII/86ACatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/84 : Groups of Galaxies.
