We investigate a spectroscopic sample of 48 early-type galaxies in the rich cluster Abell 2390 at z = 0.23 and 48 early-type galaxies from a previously published survey of Abell 2218 at z = 0.18. The spectroscopic data of A 2390 are based on Multi-Object-Spectroscopy with MOSCA at the 3.5-m telescope on Calar Alto Observatory and are complemented by(More)
