On the dependence of spectroscopic indices of early-type galaxies on age, metallicity and velocity dispersion

We investigate the Mg-sigma and <fe>-sigma relations in a sample of 72 early-type galaxies drawn mostly from cluster and group environments using a homogeneous data-set which is well-calibrated onto the Lick/IDS system. The small intrinsic scatter in Mg at a given sigma gives upper limits on t...
