Abstract:
Redshifts, four-band photometry (U BJ RF IN), and astrometry are
presented for faint galaxies in four widely separated fields. We
provide the necessary information to enable well-defined,
statistically complete subsamples of faint galaxies to be constructed
from the master catalog. The redshift survey is 86% and 71% complete
to RF≤18.5 and R_F≤19, respectively, yielding 328 galaxies with
reliable redshifts to RF≤19, with a median redshift of 0.142.
Adding the galaxies from the fainter statistical sample yields a total
of 583 reliable redshifts with a median redshift of 0.202. An
additional 156 redshifts in the same fields, but not part of the
samples defined here, are also given. Of the 739 galaxy redshifts
presented, 212 are for galaxies with RF>20.

79 A1 --- Note Notes (8)
--------------------------------------------------------------------------------
Note (1): Objects in fields SA57, SA68, Her1, and Lynx2 begin with the
digit 1, 2, 3, and 4, respectively.
Note (2): In SA57 and SA68, this means the magnitude within a circular aperture
of radius 2*r1.
In Her1 and Lynx2, this means the FOCAS total magnitude (magnitude
within an area at least twice the size of that contained within the
detection isophote).
Note (3): In SA57 and SA68, the colors are derived from magnitudes measured in
a circular aperture of radius 2*r1.
In Her1 and Lynx2, the colors are derived from magnitudes measured in
a circular aperture of radius 2 arcsec.
The 5 off-scale values (MKK97= 103357, 103341, 213807, 217739, 316656)
reflect the fact that the photometry for individual objects can be
wrong due to plate defects or whatever. They clearly indicate that
the photometry in at least one band for that object is questionable.
Note (4): Objects with a redshift of 0.0000 were morphologically classified as
galaxies, but spectroscopically found to be stars.
Note (5): q = min[6, min(1, Ndef) + 2 Ndef + Nprob], where Ndef and Nprob are
the number of definite and probable features, respectively.
Note (6): (A---OO): multi-hole or multi-slit spectrum from the specified mask
(cross-reference to column 1 in Table 5)
(a---z): long-slit or multi-fiber spectrum from the specified
observing run (cross-reference to column 1 in Table 3)
(1) Spinrad, 1980, private communication;
(2) Turner, 1980, private communication;
(3) Based on observations obtained at the W. M. Keck Observatory,
which is operated jointly by the California Institute of
Technology and the University of California.
Note (7): If this value is -1, then all galaxies brighter than this galaxy in F
which are within the field-of-view of this galaxy's primary mask have
q>2 redshifts.
Note (8): B: special target of the mask, selected as a bright galaxy;
C: special target of the mask, selected as a member of a cluster of
galaxies;
J: special target of the mask, selected as a member of a faint
J-selected sample;
N: special target of the mask, selected as a candidate NELG;
R: special target of the mask, selected as a radio source;
U: special target of the mask, selected as a UV-excess source;
X: not targeted by the mask, but accidentally fell within a slitlet or
slit targeted at a different object.
