VII/251 SBS/Zwicky cluster relation (Gyulzadian+, 2008) ================================================================================ On the Relation of Second Byurakan Surevy galaxies with Zwicky clusters. I. Data. Gyulzadian M.V., Petrosian A.R. =2008Ap.....51..349G ================================================================================ ADC_Keywords: Galaxy catalogs ; Clusters, galaxy ; Radial velocities Keywords: SBS galaxies - clusters of galaxies Abstract: In the same area covered by Second Byurakan Survey and CGCG, there are 1677 SBS galaxies, of which 892 are positioned inside the contours of Zwicky clusters. Data on these galaxies and respective clusters are presented in different tables, according to whether they are galaxies which are members of clusters or their substructures, probable or possible members. Projection cases are considered separately.

Stepanian, 2005RMxAA..41..155S. Note (G3): Abell clusters, Abell (1958, Cat. VII/4), coincident with Zwicky clusters denominations are given. Note (G4): the cluster types are comp. = Compact: clusters show a single outstanding concentration among the bright member galaxies. Within this concentration ten or more galaxies appear in actual contact. Many of these clusters display a high degree of spherical symmetry. m.comp. = Medium compact: clusters characterized either by a single concentration where, however, the ten brightest galaxies are not in contact but separated by several of their owen diameters, or by several distinct condensations, some of which may be quite compact. open = clusters without obvious condensations, but in various locations the number of galaxies per square degree is at least five times as great as in the surrounding field, so that the cluster appears as a cloud superposed on the background. -------------------------------------------------------------------------------- Acknowledgements: Marieta Gyulzadian, mgyulz@bao.sci.am History: * 03-Mar-2008: Tables received from Author * 26-May-2008: File 'sbs.dat' with positions and redshift of SBS galaxies kindly supplied by the author ================================================================================ (End) Patricia Vannier [CDS] 03-Mar-2008
