A photometric and redshift catalog of galaxies in the field of the ric
h galaxy cluster Abell 2390 (z = 0.228) is presented as part of the CN
OC cluster redshift survey carried out at the Canada-France-Hawaii Tel
escope (CFHT) using the MOS imaging multiobject spectrograph. Using fi
ve separate fields, the imaging and spectroscopic observations cover a
strip of approximately 7.'3 X 43.'2, centered on the cluster. Redshif
ts 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.
