Scientific paper

We request five 24 hour observing sessions at ATCA, Ceduna, Mopra, Hobart, Parkes, Tidbinbilla (and Hartrao if available) for running 8.4 GHz observations to determine coordinates at a milliarcsec accuracy level for 518 flat-spectrum sources in the declination zone [-40, -90]. We will also produce estimates of correlated flux density and source structure. The output catalogue of source positions will be of use for phase-referencing observations at the LBA, as a calibrator pool for the ATCA, ALMA, and SKA, for space navigation, and as a source list for geodetic observations. The success rate of previous observation was 97%. Even considering a conservative success rate estimate of 75%, the pool of known southern calibrators is expected to increase by more than a factor of 2 and the density of known calibrator at the southern hemisphere will match the density of known calibrators in the northern hemisphere. These observations will help to extend a complete flux-limited sample of compact radio sources that currently is limited by declination > -40deg to the whole sky. Our goal is to increase the density of calibrators, so it will match the density in the northern hemisphere.
