The field is centered on the European Large Area ISO Survey S1 region and has a total area of 3.9°. We describe the observations and calibration, source extraction, and cross-matching to infrared sources. Two catalogs are presented: one of the radio components found in the image and another of radio sources with counterparts in the infrared and extracted from the literature. 1366 radio components were grouped into 1276 sources, 1183 of which were matched to infrared sources. We discover 31 radio sources with no infrared counterpart at all, adding to the class of Infrared-Faint Radio Sources. Description: The radio observations were carried out on 27 separate days between 2004 January 9 and 2005 June 24 with the ATCA, with a total net integration time on the pointings of 231 h, in a variety of configurations to maximize the (u,v) coverage.

Note (1): In some cases, sources were split up into sub-components, resulting in component numbers such as "C5" and "C5.1". However, this is no anticipation of the grouping of components to sources, which was carried out independently. Note (2): In the case of single-component sources, this is identical to the source name used in table 5. This is the formal IAU designation and should be used in the literature when referring to this component. Note (3): These include the formal uncertainties derived from the Gaussian fit together with a potential systematic error in the position of the calibrator source of 0.1 arcsec. Note (4): If a deconvolution was not possible, no value is given.

Note (1): In the case of single-component sources, this is the radio position of the component. In the case of multi-component sources with good infrared identification, the SWIRE position is used. In the case of multi-component sources without infrared identification, the coordinates are a flux-weighted mean of the components' coordinates. Note (2): In the case of extended or multiple-component sources, the flux density has been integrated over the source region, rather than taking the sum of its constituent components. Note (3): Aperture-corrected flux densities have been used unless the source was clearly extended, in which case the flux in a Kron aperture has been used. Note (4): Code as follows: f = based on the far-infrared-radio relation; m = based on morphology; l = based on classification taken from the literature. Note (5): As described in the text, performed for double radio sources. A "-" indicates failure, a "x" success of the two parts of the test (separation and flux density ratio of the constituents).
