Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

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.
