Query: A catalogue of velocities in the cluster of galaxies Abell 85   We present a catalogue of velocities for 551 galaxies (and give the
coordinates of 39 stars misclassified as galaxies in our photometric plate
catalogue) in a region covering about 100'$\times$100' (0.94$\times$0.94 Mpc
for an average redshift of 0.0555, assuming H$_\circ$=50 km s$^{-1}$
Mpc$^{-1}$) in the direction of the rich cluster Abell 85. This catalogue
includes previously published redshifts by Beers et al. (1991) and Malumuth et
al. (1992), together with our 367 new measurements. A total of 305 galaxies
have velocities in the interval 13350-20000 km s$^{-1}$, and will be considered
as members of the cluster. Abell 85 therefore becomes one of the clusters with
the highest number of measured redshifts; its optical properties are being
investigated in a companion paper.
