Abstract

A deep survey of the European Large Area ISO Survey (ELAIS) field in the southern celestial hemisphere (hereinafter S1) has been carried out with the Australia Telescope Compact Array (ATCA) at 1.4 GHz. The S1 region, covering about 4 square degrees, has been also surveyed in the mid- and far-infrared (5-200 $\mu$m) with the Infrared Space Observatory (ISO). The radio survey provides uniform coverage of the entire S1 region, with a sensitivity ($5\sigma$) of 0.4 mJy over the whole area and 0.2 mJy in the center. To this sensitivity, virtually all the radio counterparts of the far-infrared extragalactic ISO sources should be detected. This paper presents a radio sample--complete at the 5$\sigma$ level--consisting of 581 sources detected at 1.4 GHz. Of these radio sources, 349 have peak flux density in the range 0.2-1 mJy, forming a new homogeneous sample of sub-mJy radio sources. Due to its size, depth and multi-waveband coverage, the sample will allow us to study in greater detail the sub-mJy radio source population.

The full catalogue will be available from http://athena.ph.ac.uk/

Catalogue

The catalogue contains a total of 621 components, and reports the source name, the peak flux density $S_p$ (in mJy), the integrated flux density $S_t$ (in mJy), the source position (right ascension and declination at equinox J2000), the FWHM of the major and minor axes, the positional angle of the major axis, the signal-to-noise ratio and a character as a comment about the deconvolution outcome (D=deconvolution of source size from beam OK, P=deconvolution gave result close to point source, F=deconvolution failed, E=multiple source). Whenever the deconvolution of the source size from the beam failed (F), the fitted parameters (instead of the deconvolved ones) are reported in the catalogue. For double or multiple sources the components are labeled `A', `B', etc., followed by a line labeled `T' in which parameters for the total source are given. The position of the total source has been computed as the flux-weighted average position for all the components. In Table 1 the first page of the catalogue is shown as an example.
