S-PASS (S-Band Polarization All-Sky Survey) 2.3-GHz Source Catalog

Listed in IVOA Registry (Virtual Observatory)

The S-band Polarization All-Sky Survey (S-PASS) has observed the entire southern sky using the 64-meter Parkes radio telescope at 2.3 GHz with an effective bandwidth of 184 MHz.

Description

The surveyed sky area covers all Declinations < 0 degrees. To analyze compact sources the survey data have been re-processed to produce a set of 107 Stokes I maps with 10.75-arcminute resolution and the large scale emission contribution filtered out.

In this paper, the authors use these Stokes I images to create a total intensity southern-sky extragalactic source catalog at 2.3 GHz. The source catalog contains 23,389 sources and covers a sky area of 16,600 deg<sup>2</sup>, excluding the Galactic plane for latitudes |b| < 10 degrees. Approximately 8% of the catalogued sources are resolved.

S-PASS source positions are typically accurate to within 35 arcseconds. At a flux density of 225 mJy, the S-PASS source catalog is more than 95% complete, and ~94% of S-PASS sources brighter than 500 mJy/beam have a counterpart at lower frequencies. The observations were carried out over the period from October 2007 to January 2010 using the Parkes S-band receiver.

The S-band receiver is a package with: a system temperature T<sub>sys</sub> = 20K, a beam Full Width at Half Maximum (FWHM) of 8.9 arcminutes, and a circular polarization front-end that is ideal for linear polarization observations with single-dish telescopes.
