Abstract:
A photometric and redshift catalog of galaxies in the field of two
rich galaxy clusters, MS 1621.5+2640 (z=0.4275) and MS 0302.7+1658
(z=0.4245), 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 strips cantered on each cluster of approximately 23.3'x9.0', and
7.9'x9.0', for MS 1621.5+2640 and MS 0302.7+1658, respectively.
Redshifts for 371 galaxies, primarily ranging in magnitude from r=20
to 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 0302.7+1658, 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).
1 pix = 0.3128"
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
88: no explained
99: observed spectroscopically but no redshift obtained
