Abstract:
    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 A2390 are based on multi-object spectroscopy
    using the multi-object spectrograph for Calar Alto at the 3.5-m
    telescope on Calar Alto Observatory and are complemented by
    ground-based imaging using the 5.1-m Hale telescope and Hubble Space
    Telescope (HST) observations in the F555W and F814W filters.
