The second epoch Molonglo Galactic Plane Survey (MGPS-2) was carried out at 843 MHz with the Molonglo Observatory Synthesis Telescope (MOST) in its upgraded wide-field capability. The survey consists of 4.3 x 4.3 degree mosaic images with a 45 x 45 '' cosec(dec) restoring beam. It covers the range |b| < 10 degrees and 245 < l < 365 degrees and is the Galactic counterpart to the Sydney University Molonglo Sky Survey (SUMSS) which covers the whole southern sky with declination < -30 degrees.

The first epoch Molonglo Galactic Plane Survey (MGPS-1) is described here.


People who are involved in the MGPS-2 survey are

It is also closely related to the SUMSS survey, and much of the work has been done in common with SUMSS.

Data products

The main data products from MGPS-2 are the set of 130 4.3 x 4.3 degree mosaic images and a compact source catalogue.

  • The mosaics are available here (most of the mosaics are listed under Galactic, but there are some borderline regions that are in Extragalactic)
  • The catalogue is available online (mgpscat.Aug-15-2007 and will be available on CDS in the near future
