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).
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
99: observed spectroscopically but no redshift obtained
