Abstract:
We analyze photometry and spectroscopy of a sample of 63 clusters at
0.3≤z≤0.9 drawn from the Las Campanas Distant Cluster Survey to
empirically constrain models of cluster galaxy evolution.
Our data originate from a variety of telescopes and instruments. The
candidate galaxy clusters are identified using drift-scan images and
techniques described briefly below for context but in full detail by
Gonzalez et al. (2001, Cat. J/ApJS/137/117).
