Abstract
A survey of the Galactio plane in the longitute range -20 <= l <= 120^o
for Galactic latitude |b| <= 0.8 has been carried out at 1400 MHz
using the VLA in the B configuretion. 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 25 mJy for sources smaller than ~20" in diameter
although sources as faint as 8 mJy 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
comprehansive bibliography is included) and from the IRAS PSC. An extensive
analysis of the integrity and completeness of the survey os presented here;
in separate publications, we discuss the source content of the survey as
derived from statistical analyses of the spatial distribution of the sources
and from radio, optical and IR followup observations.
Each of the 1992 sources has one record in the the database. The maximum
record length is 98 characters, and the format is as follows:
Columns Content
- 1-13 Source Name - The name of the sources is derived from Galactic
Longitude and Latitude of the Source, and remember that the
catalog is sorted by Longitude.
- 16-26 Right Ascension (B1950)
- 28-38 Declination (B1950)
- 41-45 Peak Flux (mJy)
- 47-51 Integrated Flux (mJy)
- 52 Comment on Flux Determination - If the column is blank, flux
was determined by a two dimentional gaussian fit; and if the
column has a '+' in it, the flux was determined by summing
the points inside a polygon which determines the boundary of
the source.
- 54-57 Size of the Source (arcseconds)
- 60-63 Distance from the Field Center (arcminutes)
- 67-98 Comments - Explanation for the comments are as follows:

- INT=xx The integrated flux density (xxx in mJy) derived
from a region of diffuse emission surrounding the
