Molonglo Observatory Synthesis Telescope Supernova Remnant Catalog

A catalog of supernova remnants (SNR) in the southern Galaxy within the Galactic Plane area 245 degrees <= galactic longitude l_II <= 355 degrees, galactic latitude |b_II| <~ 1.5 degrees has been produced from observations made in a series of 650 overlapping fields at 0.843 GHz (35.6 cm) with a spatial resolution of 43" using the Molonglo Observatory Synthesis Telescope (MOST). This table contains information on 57 known SNR (listed in Table MSC.A of the reference paper), 18 SNR newly discovered in this survey (Table MSC.B), 16 possible SNR (Table MSC.C), and 2 reclassified SNR (discussed in Section 3.3 of the reference paper), for a total of 93 SNR. This table was created by the HEASARC in March 2007 based on the CDS table J/A+AS/118/329, file msc.dat. This is a service provided by NASA HEASARC .
