Abstract:
    The S-band Polarisation All-Sky Survey (S-PASS) has observed the
    entire southern sky using the 64-metre Parkes radio telescope at
    2.3GHz with an effective bandwidth of 184MHz. The surveyed sky area
    covers all declinations DE<0{deg}. To analyse compact sources the
    survey data have been re-processed to produce a set of 107 Stokes I
    maps with 10.75-arcmin resolution and the large scale emission
    contribution filtered out. In this paper we use these Stokes I images
    to create a total intensity southern-sky extragalactic source
    catalogue at 2.3GHz. The source catalogue contains 23389 sources and
    covers a sky area of 16600deg^2^, excluding the Galactic plane for
    latitudes |b|<10{deg}. Approximately 8% of catalogued sources are
    resolved. S-PASS source positions are typically accurate to within
    35-arcsec. At a flux density of 225mJy the S-PASS source catalogue is
    more than 95% complete, and ~94% of S-PASS sources brighter than
    500mJy/beam have a counterpart at lower frequencies.

Description:
    Observations were carried out over the period October 2007 to January
    2010 using the Parkes S-band receiver. The S-band receiver is a
    package with: a system temperature Tsys=20K, a beam Full Width at Half
    Maximum (FWHM) of 8.9-arcmin, and a circular polarisation front-end
    ideal for linear polarisation observations with single-dish
    telescopes.

Note (1): We stress that the uncertainties in peak and integrated flux densities
 do not include any correction for flux scaling errors.
Note (2): Errors of -1 indicate a fitting error or nearly-circular source, where
 major and minor axis errors and position angle are poorly defined.
Note (3): If a source has been well fitted, the residuals will be small.
