Central Mg2 indices for early-type galaxies.

GOLEV V., PRUGNIEL P., SIMIEN F. and LONGHETTI M.

Abstract (from CDS):

We present 210 new measurements of the central absorption line-strength Mg2 index for 87 early-type galaxies drawn from the Prugniel & Simien (1996A&A...309..749P) sample. 28 galaxies were not observed before. The results are compared to measurements published previously as available in HYPERCAT, and rescaled to the Lick system. The mean individual internal error on these measurements is 0.009mag±0.003mag and the mean external error is 0.012mag±0.002mag for this series of measurements.
