In order to understand if the differences between the SSRS of Da Costa et al. (which is diameter‐limited) and the CfA survey (which is magnitude‐limited) are real or induced by the different selection criteria, the CfA survey has been directly compared with a diameter‐limited sample covering the same region of the sky (UDLS, Bardelli et al. 1991, Zucca et al. 1991). In this paper we present the data for the galaxies in the UDLS sample, in an updated version which collects velocity information from the literature until June 1993, leaving us with a velocity completeness better than ˜ 95%.
