cds-question@unistra.frgalaxiescatalogsradial-velocitygalaxy-kinematicsWe 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 600{AA} centered on the Mg I b triplet at {lambda}~5175{AA}. Velocity dispersions were measured using the Tonry & Davis (1979AJ.....84.1511T) cross-correlation method, with a typical accuracy of 6%. A detailed comparison with other data sources is made.1998AJ....116.2738Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/116/2738CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/26 : Uppsala General Catalogue of Galaxies (UGC) (Nilson 1973)VII/118 : NGC 2000.0 (Sky Publishing, ed.
