1990AJ....100....1F POPULATION STUDIES IN GROUPS AND CLUSTERS OF GALAXIES. III. A CATALOG OF GALAXIES IN FIVE NEARBY GROUPS HENRY C. FERGUSON Department of Physics and Astronomy, Center for Astrophysical Sciences, The Johns Hopkins University, Baltimore, Maryland 21218 ALLAN SANDAGE The Observatories of the Carnegie Institution of Washington, 813 Santa Barbara Street, Pasadena, California 91101 and Department of Physics and Astronomy, Center for Astrophysical Sciences, The Johns Hopkins University, Baltimore, Maryland 21218 and Space Telescope Science Institute, 3700 San Martin Drive, Baltimore, Maryland 21218 Received 6 February 1990; revised 3 April 1990 ABSTRACT Five nearby groups of galaxies have been surveyed using large-scale plates from the 2.5 m duPont Telescope at Las Campanas Observatory. Catalogs of galaxies brighter than B_T_~20 are presented for the Leo, Dorado, NGC 1400, NGC 5044, and Antlia groups. A total of 1044 galaxies are included, from visual inspection of 14 plates, covering 31^deg^ square. Galaxies have been classified in the extended Hubble system, and group memberships have been assigned based on velocity (where available) and morphology. About half the galaxies listed are likely members of one of the nearby groups. The catalogs are complete to B_T_~18, although the completeness limits vary slightly from group to group. Based on King model fits to the surface density profiles, the core radii of the groups range from 0.3 to 1 Mpc, and central densities range from 120 to 1900 galaxies Mpc^-3^ brighter than M_B_T__ = - 12.5. Dynamical analysis indicates that all of the groups are likely to be gravitationally bound.
