        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.
