A Catalog of Small-Diameter Radio Sources in the Galactic Plane
Abstract
A survey of the Galactic plane in the longitude range -20^deg^ <= l <= 120^deg^ for Galactic latitudes |b| <= 0.8^deg^ has been carried out at 1400 MHz 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 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 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 analyses of the spatial distribution of the sources and from radio, optical and infrared followup observations.
