The CNOC cluster redshift survey catalogs. IV. MS 1358.4+6245 and MS 1008.1-1224

Photometric and redshift catalogs of galaxies in the field of two rich galaxy clusters, MS 1358.4 + 6245 (z = 0.328) and MS 1008.1-1224 (z = 0.306), are presented as part of the CNOC cluster redshift survey carried out at the Canada-France-Hawaii Telescope (CFHT) using the MOS imaging multiobject spectrograph. The imaging and spectroscopic observations cover a mosaic of three MOS fields in the north-south direction of a total area of approximately 23.'3 x 9.'0 for MS 1358.4 + 6245 and a single field of 7.'9 x 9.'0 for MS 1008.1-1224. Redshifts for 361 galaxies, primarily ranging in magnitude from r = 20 to r = 22, and Gunn r and g photometry for 3015 galaxies to I = 24 mag were obtained. The data set is also presented graphically in several forms. The magnitude, color, and geometric selection functions for the redshift sample are presented and discussed.
