J/AJ/130/586   Compact radio sources in the galactic plane        (White+, 2005)

New catalogs of compact radio sources in the galactic plane. White R.L., Becker R.H., Helfand D.J. <Astron. J., 130, 586-596 (2005)> =2005AJ....130..586W
ADC_Keywords: Radio sources ; Galactic plane Keywords: catalogs - Galaxy: general - H II regions - radio continuum: ISM - supernova remnants - surveys Abstract: Archival data have been combined with recent observations of the Galactic plane using the Very Large Array to create new catalogs of compact centimetric radio sources. The 20cm source catalog covers a longitude range of -20°<l<120° the latitude coverage varies from ±0.8° to ±2.7°. The total survey area is about 331°2; coverage is 90% complete at a flux density threshold of about 14mJy, and over 5000 sources are recorded. The 6cm catalog covers 43°2 in the region -10°<l<42°, |b|<0.4° to a 90% completeness threshold of 2.9mJy; over 2700 sources are found. Both surveys have an angular resolution of about 6". These catalogs provide a 30% (at 20cm) to 50% (at 6cm) increase in the number of high-reliability compact sources in the Galactic plane, as well as greatly improved astrometry, uniformity, and reliability; they should prove useful for comparison with new mid- and far-infrared surveys of the Milky Way.

Note (1): Sources that match more than once are listed multiple times, e.g., a 6cm source that matches two 20cm sources is listed twice, once with each 20cm counterpart.
Global Notes: Note (G1): Derived from elliptical Gaussian fits. Note (G2): Source flag, defined as follows: o = in our original catalog (Zoonematkermani et al. 1990, Cat. J/ApJS/74/181; Helfand et al. 1992ApJS...80..211H); OH = not continuum sources but instead are detected through their 1611MHz OH maser emission (Becker, White & Proctor 1992AJ....103..544B). c = in the old 6cm catalog; l = in the old 20cm catalog; cl = in both catalogs; blank = in neither catalog; * = 20cm-only source very close to the 6cm survey edge.
