The CNOC Cluster Redshift Survey Catalogs. II. Abell 2390

Abstract

A photometric and redshift catalog of galaxies in the field of the rich galaxy cluster Abell 2390 (z = 0.228) is presented as part of the CNOC cluster redshift survey carried out at the Canada-France-Hawaii Telescope (CFHT) using the MOS imaging multiobject spectrograph. Using five separate fields, the imaging and spectroscopic observations cover a strip of approximately 7.′3 × 43.′2, centered on the cluster. Redshifts for 327 galaxies, primarily ranging in magnitude from r = 17 to 22, were obtained. The data set is also presented graphically in several forms. The magnitude, geometric, and color selection functions for the redshift sample are discussed and presented.
