Abstract:
We present a catalog of 246 radio sources found in the central 1°
of the COSMOS field at 1.4GHz. The VLA pilot project data have a
resolution of 1.9"x1.6" and an rms noise limit of
∼25-100µJy/beam covering 0.837°^2. About 20 radio sources are
clearly extended, and most of them appear to be double-lobed radio
galaxies. We find evidence for a cluster of seven radio galaxies with
an extent of ∼10' southeast of the COSMOS field center.
Description:
The COSMOS field was observed at 1.4GHz for 10hr in total on 2003
August 1 with the NRAO Very Large Array (VLA) in its A configuration.

Note (1): In units of mJy/beam.
Note (2): Radio sources with multiple Gaussian fits are flagged by a "y"
and listed separately in Table 3. For these sources no uncertainties
in the coordinates and flux densities were determined (indicated by
null values). The uncertainty for the absolute coordinates is on the
order of ∼0.05" as derived from comparison between the results from
two source detection algorithms SAD (search and destroy) and SFIND
(see also section 3).
