Abstract:
A photometric and redshift catalog of galaxies in the field of two
rich galaxy clusters, MS 0015.9+1609 (z=0.5481) and MS 0451.5-0305
(z=0.5386), is 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 single field of approximately 7.6'x9.1', centered on each
cluster. Redshifts for 247 galaxies, primarily ranging in magnitude
from r=20 to r=22, 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 0015.9+1609 and MS 0451.5-0305, 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
3: E+A
4: Sbc
5: emission-line (Irr)
6: active galactic nucleus/ quasar
77: star
