Abstract:
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 Canadian Network for
Observation Cosmology (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'x9.0' for MS 1358.4+6245 and a single
field of 7.9'x9.0' 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 r=24mag 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.

Note (1): The identification number is made of:
- THe first digit denotes the field of origin for the galaxy with
the numbers 1, 2, 3, 4, and 5 representing the central, east 1,
west 1, east 2 and west 2 field, respectively.
- The second digit indicates whether the object is observed in one
field or in an overlapping area from two fields. In the former,
the second digit is 0; and in the latter, the second digit
represents the field number of the overlapping field.
- The last four digits denote the object number for each object
within its own field, starting from the southern edge of the
field, increasing to the north.
For MS 1008.1-1224, only the central field was observed, so the field
designation digits are not listed.
Note (2): Offset from the first rank galaxy (positive is east and north).
