cds-question@unistra.frgalaxiesspectroscopygalaxy-clustersCentral velocity dispersions, Mg_2_ line indices, and radial velocities for 220 E and S0 galaxies are derived on basis of intermediate resolution spectroscopy. Galaxies in the following clusters have been observed: Abell 194, Abell 539, Abell 3381, Abell 3574, S639, S753, Doradus, HydraI (Abell 1060), and Grm15. The spectra cover 50 or 100nm centered on the magnesium triplet at 517.7nm. In this catalog we give the mean values of the parameters. The central velocity dispersion and the Mg_2_ line indices have been aperture corrected to a circular aperture with a diameter of 1.19h^-1^kpc, equivalent to 3.4arcsec at the distance of the Coma cluster. Values are also given for a circular aperture with radius equal to the effective radius of the galaxy (cf. Jorgensen et al. 1995, Cat. J/MNRAS/273/1097). The Mg_2_ indices are consistent with the Lick system. The typical uncertainty of the central velocity dispersion is 0.036 in log({sigma}), the typical uncertainty of Mg_2_ is 0.013. Further, literature data (velocity dispersions and Mg_2_ indices) for the clusters A194, DC2345-28 and Coma (A1656) have been brought on a homogeneous system and aperture corrected to the aperture sizes given above. The literature data are from Davies et al. (1987ApJS...64..581D), Dressler (1987ApJ...317....1D), Dressler & Shectman 1988 (J/AJ/95/284), Lucey & Carter (1988MNRAS.235.1177L), Lucey et al.
