A catalogue of velocities in the direction of the cluster of galaxies Abell 496

We present a catalogue of velocities for 466 galaxies in the direction of t he cluster Abell 496, in a region covering about 160' x 160' (9.2 x 9.2 Mpc for an average redshift for Abell 496 of 0.0331, assuming H-0 = 50 km s(-1 ) Mpc(-1)). This catalogue includes previously published redshifts by Prous t et al. (1987), Quintana & Ramirez (1990) and Malumuth et al. (1992), reds hifts from the CfA redshift survey, together with our new measurements. A t otal of 274 galaxies have velocities in the 7800 - 11800 km s(-1) interval, and will be considered as members of the cluster. Abell 496 therefore beco mes one of the few clusters with a high number of measured redshifts; its p hysical properties are investigated in a companion paper.
