THE CNOC CLUSTER REDSHIFT SURVEY CATALOGS - VI - MS-0015.9-0451.5-0305(1609 AND MS)

A photometric and redshift catalog of galaxies in the field of two ric h galaxy clusters, MS 0015.9 + 1609 (z = 0.5481) and MS 0451.5-0305 (z = 0.5386), is presented as part of the CNOC cluster redshift survey c arried out at the Canada-France-Hawaii Telescope (CFHT) using the MOS imaging multiobject spectrograph. The imaging and spectroscopic observ ations cover a single held of approximately 7.'6 x 9.'1, centered on e ach cluster. Redshifts for 247 galaxies, primarily ranging in magnitud e from r = 20 to r = 22, were obtained. The data set is also presented graphically in several forms. The magnitude, color, and geometric sel ection functions for the redshift sample are presented and discussed.
