Molonglo Galactic Plane Survey 2nd Epoch Compact Source Catalog

Listed in IVOA Registry (Virtual Observatory)

Description

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/81B">CDS Cat.

VIII/81B</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.

Positions in the catalog are accurate to 1" - 2". The authors have carried out an analysis of the compact source density across the Galactic plane and find that the source density is not statistically higher than the density expected from the extragalactic source density alone. This HEASARC table was created in January 2008 based on <a href="cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/382/382">CDS catalog J/MNRAS/382/382</a> file mgpscat.dat.
