General study of group membership. II - Determination of nearby groups
We present a whole sky catalog of nearby groups of galaxies taken fromthe Lyon-Meudon Extragalactic Database. From the 78,000 objects in thedatabase, we extracted a sample of 6392 galaxies, complete up to thelimiting apparent magnitude B0 = 14.0. Moreover, in order to considersolely the galaxies of the local universe, all the selected galaxieshave a known recession velocity smaller than 5500 km/s. Two methods wereused in group construction: a Huchra-Geller (1982) derived percolationmethod and a Tully (1980) derived hierarchical method. Each method gaveus one catalog. These were then compared and synthesized to obtain asingle catalog containing the most reliable groups. There are 485 groupsof a least three members in the final catalog.
| Redshifts of galaxies in some southern groups and clusters
A table of redshifts for 67 galaxies in southern groups and clusters ispresented. The galaxies are found in or near Sersic 40/6, A496, Klemola44, 2354-35, Klemola 2, Pavo, Sersic 149/5, Sersic 149/10, 2355-35,0001-36, 0003-35, and 0007-36.
