Abstract:
Photometric and redshift catalogs of galaxies in the field of two rich
galaxy clusters: MS 1224.7+2007 (z=0.327) and MS 1512.4+3647 (z=0.372)
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
span three contiguous MOS fields in the east-west direction for MS
1512.4+3647, covering a total area of approximately 8.0'x27.3'. A
single field of 7.1'x9.0' was obtained for MS 1224.7+2007. Redshifts
for 287 galaxies in the MS 1512.4+3647 fields and 75 galaxies in the
MS 1224.7+2007 field (primarily ranging in magnitude from r=18-22)
were obtained. The spectroscopic information in this paper is
supplemented by photometric information for all galaxies in the fields
down to Gunn r=21mag. 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 1224.7+2007, 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).

Note (3): the classification is:
1 and 2: elliptical

4: Sbc
5: emission-line (Irr)
6: active galactic nucleus/ quasar
77: star
88: no explained
