Each group contains four or more galaxies, has an estimated mean surface brightness brighter than 26.0 magnitude per arcsec^2^ and satisfies an isolation criterion. Dynamical parameters were derived for 92 of the 100 groups, which are listed in file "dynamics.dat"; the Hubble constant was assumed to be Ho=100km/s/Mpc. Data about individual galaxies in these groups are merged into the "galaxies.dat" file; these data include photometric parameters, morphology, redshifts and absolute magnitudes originally published in four different papers. They result from CCD observations at CFHT (Canada-France-Hawaii Telescope) in 1983-1985. Redshifts were observed at the 1.5m telescope of the F.L. Whipple Observatory on Mt. Hopkins, Arizona, over the period 1984-1986, in wavelength range 470-710nm; the remaining fainter galaxies were observed with the CFHT.Galaxy clustersGalaxiesOptical astronomyRedshiftedPhotometryGalaxy kinematicsgalactic-and-extragalactic-astronomyobservational-astronomycosmologyhttps://dc.g-vo.org/rr/q/lp/custom/CDS.VizieR/VII/213https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/2131982ApJ...255..382Hhttp://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VII/213Cone search capability for table VII/213/groups (Catalog of groups (1982 paper, and errata))Cone search capability for table VII/213/galaxies (Photometric and Velocity data for galaxies (combined tables from 1989 and 1992 papers))Hickson P.CDS1999https://cds.unistra.fr/vizier-org/licences_vizier.htmlCDS support team <cds-question@unistra.fr>DatasetAstroObjectsastronomy
