Molonglo Galactic Plane Survey 2nd Epoch Compact Source Catalog

This table contains the Molonglo Galactic Plane Survey 2nd Epoch (MGPS-2) Compact Source Catalog. The MGPS-2 was carried out with the Molonglo Observatory Synthesis Telescope (MOST) at a frequency of 843 MHz and with a restoring beam of 45" x 45" cosec |(delta)|, where delta is the declination, making it the highest resolution large-scale radio survey of the southern Galactic plane to date. It covers the range |b| < 10 degrees and 245 < l < 365 degrees, where l and b are the Galactic longitude and latitude, and is the Galactic counterpart to the SUMSS (<a href="cdsarc.cds.unistra.fr/ftp/cats/VIII/81">CDS Cat.

VIII/81</a>) Catalog which covers that portion of the southern sky with delta < -30 degrees, |b| > 10 degrees. This version of the catalog (15-Aug-2007) consists of 48850 compact sources, made by fitting elliptical Gaussians in the MGPS-2 mosaics to a limiting peak brightness of 10 mJy/beam. The authors used a custom method (described in the associated reference publication) to remove extended sources from the catalog.
