Abstract:
We present redshifts and stellar velocity dispersions for about 40
galaxies in each of 14 rich clusters from the southern cluster survey
of Abell & Corwin (1983, Early Evolution of the Universe and Its
Present Structure, p.179, Eds. Abell & Chincarini, Reidel, Dordrecht,
Holland). The clusters cover a wide range of richnesses and Abell and
Bautz-Morgan types, our aim being to compile a large, homogeneous
database for examining and comparing dynamical phenomena and
morphological properties. Further papers will present photometry for
the clusters and an analysis of the database.

Note (1): R: ratio of peak height to noise in the cross-correlation function,
which is used to calculate the errors and is a measure of the
combined effects of noise and template mismatch (see Tonry &
Davis, 1979AJ.....84.1511T 1979AJ.....84.1511T).
Note (2): Method by which velocities were obtained:
Blank: cross-correlation
E: emission lines
A: absorption features
E+A: emission and absorption features
