Description:
    A photometric and redshift catalog of galaxies in the field of the
    rich galaxy cluster Abell 2390 (z=0.228) 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. Using five separate fields,
    the imaging and spectroscopic observations cover a strip of
    approximately 7.3'x43.2', centered on the cluster. Redshifts for 327
    galaxies, primarily ranging in magnitude from r=17 to 22, were
    obtained. The data set is also presented graphically in several forms.
    The magnitude, geometric, and color selection functions for the
    redshift sample are discussed and presented.

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.
Note (2): Offset from the first rank galaxy (positive is east and north).
