  We present a catalog of 246 radio sources found in the central 1 degree 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 ~25-100uJy/beam covering 0.837 sqrdeg.
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 7 radio sources
with an extent of ~10' southeast of the COSMOS field center. This VLA pilot
project was undertaken to demonstrate the feasibility of wide-field mosaicking
at 2'' resolution at 1.4GHz using the VLA in its A array configuration. The
7-point mosaic data was used to develop the techniques necessary for reduction
and analysis. These data will provide the initial astrometric frame for the
optical (ground- and space-based) data of the COSMOS 2 sqrdeg survey. In
addition, it demonstrates the feasibility of obtaining deep (rms ~ few uJy)
radio imaging of this field at 1.4GHz, since the brightest radio emission peak
detected within the area covered has a flux density of 13mJy/beam and no strong
side-lobes from sources surrounding the COSMOS field were detected. Comparison
of the number counts to other deep radio surveys shows that the COSMOS field is
a representative deep field in the radio domain.
