| Abstract | We present new spectroscopic data for 532 early-type galaxies, predominantly Abell cluster members with cz<12000kms-1. We tabulate 919 individual measurements, from six observing runs, for recession velocity, cz, central velocity dispersion, σ, and magnesium line-strength indices, Mg2 and Mgb. The median estimated error, per measurement, in σ is 5 per cent. The Mg2 line-strength dat ... |
