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:

                 4: Sbc

                88: no explained
