This is a catalog of 915 sources in the galactic plane between l=190 - 360 - 40 for -2 < b < 2. The l, b pair of galactic coordinates is given in columns 1 and 2 and essentially constitutes the galactic source name. The 1950 equatorial coordinates for each source are given in columns 3 and 4, and values for the peak brightness temperature and flux density are given in columns 5 and 6. The reader should refer to Section 3 of the source reference for information relating to the determination of the flux densities. Column 7 gives an estimate of the source extension in minutes of arc. Extents are given for source in nonconfused regions only. Finally, in column 8 comments on each source are included where appropriate. Identifications with known supernova remnants are included from the compilation of Clark and Caswell (1976MNRAS.174..267C). Identifications with HII regions are based principally on H109alpha recombination-line emission data, which are mostly obtained from Wilson et al. (1970A&A.....6..364W) but with some unpublished Parkes observations included also. Source search techniques: The detection of sources from the survey maps was made using an automatic search routine with the CSIRO Cyber 76 computing system. Maps were held using the NOD-2 format (see Haslam 1974,1975) in machine readable form. Each map was systematically searched for sources above the background level equivalent to a main beam brightness temperature of 0.4 K. The initial search for sources consisted of identifying those grid points in the map which exceed the mean of the four adjacent surrounding points by a nominal 0.1 K (grid point are at the Nyquist sample interval). Subsequently, the 'rough' position and flux density were refined by a source-fitting technique. The fitting procedure involved using a 16-point beam, function, where the appropriate weighting for each grid point permitted the program to interpolate to the best position for the peak of the source while taking into account nearby galactic features. The beam-fitting procedure was used either side (alternating between right ascension and declination) of the nominal position to obtain the best estimate of the position of each source. The resulting positions have an accuracy comparable to the overall positional accuracy of the survey (30" arc). Peak main beam brightness temperatures (determined by fitting the 16-point beam response function at the deduced nominal position) are also accurate to within the survey accuracy. Sources with a peak beam brightness temperature of at least 0.2 K above the background are included, except in confused regions; a point source of 0.2 K corresponds to 0.26 Jy.
