ADC_Keywords: Clusters, galaxy ; Galaxies, photometry Keywords: galaxies - galaxy groups - Shakhbazian groups Description: The largest survey of compact galaxy groups was published by Shakhbazian et al. (see cat. VII/89). This catalogue provides accurate positions of individual galaxies in the groups; photometrical properties of the Southern sky (delta not greater than +2°30') are evaluated on the basis of the COSMOS/UKST catalog of the Southern sky. The catalogue contains 373 groups; this number differs from the number in Shakhbazian's list (377 groups) by the following: => No data for groups 001 (there were already published data by other authors), 206 (could not be re-identified) 241 (could not be re-identified) 252 (is identical with 214), 301 (could not be re-identified) 353 (could not be re-identified) => Group 328 was published twice (in North and South) => Group 340 was divided in two parts (340 and 340a), according to Bettoni and Fasano ([BF95]=1995AJ....109...32B) File Summary:

The 'H' indicates positions adopted from the Hamburg Quasar Survey, and the question mark (?) indicates an inaccurate position (a note generally follows) Note (3): when only the velocity was given in the paper, the redshift was computed with z = V / 299792
