1992A&AS...95....1G Samples of dumb-bell galaxies in southern rich clusters L. Gregorini, G. Vettolani, H.R. de Ruiter and P. Parma Istituto di Radioastronomia del CNR, Via Irnerio 46,40126 Bologna, Italy Dipartimento di Fisica, Universita' di Bologna, Italy Osservatorio Astronomico, Bologna, Italy Recieved September 19; accepted November 26, 1991 Abstract - We present two optically selected samples of dumb-bell galaxies extracted from the southern extension of the Abell catalogue and we discuss the selection criteria. The first sample is a volume limited sample obtained by selecting the dumb-bell galaxies in all the 171 clusters within a comoving distance of 210h^-1^ Mpc^-1^ regardless of Bautz-Morgan classification. The second sample is constituted by dumb- bell systems belonging to the 381 clusters of BM I or I-II type. From the latter sample it is not possible to extract a volume limited sample due to the selection effect present in the Bautz-Morgan classification of the southern Abell catalogue. Key words: galaxies: clustering - galaxies: elliptical and lenticular, cD.
