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).
