The survey consists of 4.3x4.3{deg} mosaic images with 45x45''cosec{delta} 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 <-50{deg}, and 10mJy/beam at declination >-50{deg}. 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. 2003MNRAS.342.1117M https://cdsarc.cds.unistra.fr/viz-bin/cat/VIII/78 Catalog Research IsServedBy TAP VizieR generic service IsPreviousVersionOf VIII/81 IsServedBy Conesearch service related-to VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998) http://www.astrop.physics.usyd.edu.au/sumsscat/ : the SUMSS Home Page https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VIII/78 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VIII/78 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VIII/78 https://vizier.cds.unistra.fr/viz-bin/votable?-source=VIII/78 https://vizier.iucaa.in/viz-bin/votable?-source=VIII/78 http://vizieridia.saao.ac.za/viz-bin/votable?-source=VIII/78 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table VIII/78/sumsscat (The SUMSS Catalog, Version 1.7 (2006-06-01)) https://vizier.cds.unistra.fr/viz-bin/conesearch/VIII/78/sumsscat? https://vizier.iucaa.in/viz-bin/conesearch/VIII/78/sumsscat? http://vizieridia.saao.ac.za/viz-bin/conesearch/VIII/78/sumsscat?
