Description:
The Sydney University Molonglo Sky Survey (SUMSS) is being carried out
at 843MHz with the Molonglo Observatory Synthesis Telescope (MOST) in
its upgraded wide-field capability. The survey consists of 4.3x4.3deg
mosaic images with 45x45''cosecdelta resolution, covering 8000
square degrees from -30 degrees declination southwards. The survey
resolution and sensitivity (1-sigma noise limit 1mJy) are well-matched
to the NRAO VLA Sky Survey (NVSS) so that together NVSS and SUMSS will
provide a complete survey of the radio sky.
The version 1.7 (01-Jun-2006) of the catalogue consists of 205676
radio sources made by fitting elliptical gaussians in 671 SUMSS
mosaics to a limiting peak brightness of 6mJy/beam at declination
<-50deg, and 10mJy/beam at declination >-50deg. Positional
accuracies are 1-2'' for sources with S_p_>=20mJy/beam, and are always
better than 10''. The internal flux density scale is accurate to 3%.
Image artefacts have been classified using a decision tree, which
correctly identifies and rejects spurious sources in over 96% of cases.
See the SUMSS site at http://www.astrop.physics.usyd.edu.au/sumsscat/
for details about all versions of the SUMSS, and an access to the
mosaic images.
