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.1982ApJ...255..382Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/VII/213CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/117/39 : Far-IR properties of Hickson Compact Groups (Allam+, 1996)J/A+A/325/473 : HCG HI-deficiency (Huchtmeier 1997)J/AJ/123/2976 : The UZC-SSRS2 group catalog (Ramella+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VII/213https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VII/213http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VII/213https://vizier.cds.unistra.fr/viz-bin/votable?-source=VII/213https://vizier.iucaa.in/viz-bin/votable?-source=VII/213http://vizieridia.saao.ac.za/viz-bin/votable?-source=VII/213GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table VII/213/groups (Catalog of groups (1982 paper, and errata))https://vizier.cds.unistra.fr/viz-bin/conesearch/VII/213/groups?https://vizier.iucaa.in/viz-bin/conesearch/VII/213/groups?http://vizieridia.saao.ac.za/viz-bin/conesearch/VII/213/groups?GETtext/xml+votable180.050000true6.5008425.718150.005555555555555556Cone search capability for table VII/213/galaxies (Photometric and Velocity data for galaxies (combined tables from 1989 and 1992 papers))https://vizier.cds.unistra.fr/viz-bin/conesearch/VII/213/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/VII/213/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/VII/213/galaxies?GETtext/xml+votable180.050000true6.529745225.72504720.0055555555555555566/526 589 814 2254 2276 4215 4318 4433 4447 4469 4966 5829 5970 5996 6517 7442 7532 7547 8261 8557 8626-8627 8646 8787 8935 8938 8973 9417 10528 10637 11002-11003 11103 11666 11699 12120 13511 16112 16670 16784 17245 17247 17492 17525 17601 17603 17637 17866 18071 18168 18757 18775 19074 19538 19617 19619 19626 19661 19928 20029 20031 20284 20289 21218 22590 22672 22772 22828 23028 23182 24126 25721 25769 25842 27174 27226 27282 27620 27803 27872 28269 28271 28278 28377 28515 31540 31712 34664 35826 36446 36468 36621 36672 36686 36713 36740 38774 38853 40294 43913 43968 46987 47027 47951 48723 49121https://cdsarc.cds.unistra.fr/viz-bin/moc/VII/213?format=asciiOpticaldefaultVII/213/groupsCatalog of groups (1982 paper, and errata)recnoRecord number assigned by the VizieR team.
