    GROUPS OF GALAXIES WITHIN 80 MPC .2. THE CATALOG OF GROUPS AND GROUP MEMBERS
    (1992) FOUQUE, P; GOURGOULHON, E; CHAMARAUX, P; PATUREL, G
    This paper gives a catalogue of the groups and associations obtained by means of a revised hierarchical algorithm applied to a sample of 4143 galaxies with diameters D25 larger than 100 arcsec and redshifts smaller than 6000 km s-1 (the method and the groups properties are detailed in Paper I). In the present paper, the 264 groups of galaxies obtained in this way (and which contain at least 3 sample galaxies) are listed, with the loose associations surrounding them and the individual members of each aggregate as well; moreover, the location of every entity among 13 regions corresponding roughly to superclusters, is specified. Finally, 1729 galaxies belong to the groups, and 466 to the associations, i.e. the total fraction of galaxies within the various aggregates amounts to 53%.

    OBSERVATIONAL DATA FOR THE KINEMATICS OF THE LOCAL UNIVERSE .1. RADIAL-VELOCITY MEASUREMENTS
    (1992) BOTTINELLI, L; DURAND, N; FOUQUE, P; GARNIER, R; GOUGUENHEIM, L; PATUREL, G; TEERIKORPI, P
    The study of the local velocity field requires the use of a very large sample to describe as accurately as possible some prominent features of the local kinematics. The problem of collecting a large sample is made more difficult because of the Malmquist bias which plagues distance determinations. Our programme aims at determining bias-free distances for a complete sample in order to study the local velocity field. The present paper gives 303 preliminary optical and radio redshifts measured for this program at ESO, OHP and Nancay Observatories.

    OBSERVATIONAL DATA FOR THE KINEMATICS OF THE LOCAL UNIVERSE .2. 2ND SET OF RADIAL-VELOCITY MEASUREMENTS
    (1993) BOTTINELLI, L; DURAND, N; FOUQUE, P; GARNIER, R; GOUGUENHEIM, L; LOULERGUE, M; PATUREL, G; PETIT, C; TEERIKORPI, P
    This paper is the second one in a series dedicated to the study of the kinematics of the local universe. It gives 361 new optical and radio redshifts measured at ESO, OHP and Nancay Observatories.
