Description:
The catalog presents a list of redshifts for 758 Abell clusters, and
velocity dispersions for 121, published as of 1991 March. We present
another list of 33 Abell clusters with published redshifts, most of
which are probably redshifts of foreground or background galaxies
superposed on, or near, the Abell clusters. Over the past 4 years, the
published number of redshifts of member galaxies in clusters increased
by a factor of 2.0, but the number of cluster redshifts increased by
only a factor of 1.3, while the number of cluster velocity dispersions
derived from 50 or more redshifts of member galaxies increased by a
factor of 3.8 (from 6 to 23).

Note on Ref:
The present data supersede the former "SR1" (1987ApJS...63..543S 1987ApJS...63..543S).
However, the present list of references follows that in "SR1",
beginning its number from 71. The code numbers less than 71 and
used here have however been added here.
