Abstract:
We present central velocity dispersion measurements for 325 early-type
galaxies in eight clusters and groups of galaxies, including new
observations for 212 galaxies. The clusters and groups are the A262,
A1367, Coma (A1656), A2634, Cancer, and Pegasus Clusters and the NGC
383 and NGC 507 Groups. The new measurements were derived from
medium-dispersion spectra that cover 600Å centered on the Mg I b
triplet at λ∼5175Å. Velocity dispersions were measured using
the Tonry & Davis (1979AJ.....84.1511T 1979AJ.....84.1511T) cross-correlation method, with
a typical accuracy of 6%. A detailed comparison with other data
sources is made.
