Abstract:
We present a 1.4GHz catalog of 810 radio sources (560 sources in the
complete sample) found in the SSA 13 field (RA=13:12, DE=42:38). The
1.4GHz radio image was obtained from a 91hr VLA integration with an
rms noise level of 4.82uJy/beam at the field center. Optical images
in the R band (6300Å) and z band (9200Å) with 3σ detection
magnitudes of 26.1 and 24.9, respectively, were obtained from three
observing nights on the 8m Subaru Telescope. We find that 88%±2% of
the radio sources are identified with an optical counterpart.
Description:
The SSA 13 observations were made with the VLA at 1.4GHz for a total
of 104hr on nine separate observing days, from 1999 Jul 02 to 2000
Jan 14.

Note (1): The letter "N" before the number indicates that it is NOT in
the complete sample: either the peak flux density on the image is
less than 25.8 microjanskys per beam or it lies more than 15' from
the field center.
Note (2): If the radio source is composed of several discrete radio
components, these are separately listed underneath as A, B, etc.
Note (3): Individual radio components of a catalogued source are not given
separate IAU designations, but should use that of the source as a whole.
Note (4): Given by the peak image flux density divided by the rms noise.
Those sources with SNR<5.35 are not in the complete catalog.
Note (5): Corrected to the sky for all instrumental effects. The
determination of this parameter is discussed in section 2.4.
Note (6): For sources larger than 8", the position is that of the brightest
emission peak in the source, not the centroid. The minimum error is
0.010s in right ascension and 0.10" in declination, as discussed in
section 2.1.
Note (7): All instrumental and noise corrections have been made, and this
angular size is the best estimate of the true angular size or its
limit. The size of each individual radio component is also given.
The angular size limit is a strong function of SNR. Based on
simulations, we estimate that there is more than 85% confidence that
a source with a tabulated angular size is really resolved. Entries of
"-99.9" for MinAxis and "-999" for PA indicate blank values.
Note (8): Radio/optical morphology category as follows:
EG = Active galaxies with extended emission
S = stellar object
G = Isolated galaxy
Gc = Unresolved radio source located near nucleus
Gd = Radio source displaced from nucleus
Ge = Resolved radio source located near nucleus
B = Multiple systems
B2 = Radio emission from both galaxies of a binary system
Bc = Unresolved radio source located near nucleus of one galaxy
Be = Resolved radio source located near nucleus of one galaxy
C = Complex system
F = Faint object (≫24.5 to 26.0mag)
U = Unidentified
N = No Subaru data
sg = galaxy, for radio field covered only by the SDSS and not the
deeper Subaru images
su = unidentified, for radio field covered only by the SDSS and not
the deeper Subaru images
There is some subjectivity among the categories. Individual optical
identifications for radio components in a catalogued source are also
listed when applicable.
Note (9): Of the optical counterpart to the radio source (or components
where applicable). Entries of "-99.9" indicate blank values.
