Abstract:
A survey of the Galactic plane in the longitude range -20deg=<l≤120deg
for Galactic latitudes |b|=<0.8deg has been carried out at 1400MHz
using the VLA in the B configuration. We present here a catalog of the
1992 discrete sources detected in this survey which is ∼75% complete
to a limiting peak flux density of 25mJy for sources smaller than ∼20"
in diameter, although sources as faint as 8mJy and as large as 90" are
also included. The catalog includes for each entry a position accurate
to ~<3", peak and integrated flux densities, source extent, and
information on counterparts both from earlier radio surveys of the plane
(for which a comprehensive bibliography is included) and from the IRAS
point source catalog. An extensive analysis of the integrity and
completeness of the survey is presented here: in separate publications,
we discuss the source content of the survey as derived from statistical
analysis of the spatial distribution of the sources and from radio,
optical and infrared follow up observations .

intensity within a polygon enclosing the source.

Note (1):
The source name was appended with component designations a,b,c,... to
indicate that this record refers to the flux measurement of a component
of that source, and not the entire source. The position reported in
this table8 is taken from table 4 and therefore does not represent the
actual position of the source component.
