  We present catalogs of objects detected in deep images of 11 fields in 10
distant clusters obtained using WFPC-2 on board the Hubble Space Telescope. The
clusters span the redshift range z=0.37-0.56 and are the subject of a detailed
ground- and space-based study to investigate the evolution of galaxies as a
function of environment and epoch. The data presented here include positions,
photometry and basic morphological information on ~9000 objects in the fields
of the 10 clusters. For a brighter subset of 1857 objects in these areas we
provide more detailed morphological information.
