cds-question@unistra.frsurveysradio-sourcesWe have conducted a deep survey (rms noise ~=17{mu}Jy) with the Very Large Array (VLA) at 1.4GHz, with a resolution of 6arcsec, of a 1{deg}^2^ region included in the VIRMOS VLT Deep Survey. In the same field we already have multiband photometry down to I_AB_=25, and spectroscopic observations will be obtained during the VIRMOS VLT survey. The homogeneous sensitivity over the whole field has allowed to derive a complete sample of 1054 radio sources (5{sigma} limit). We give a detailed description of the data reduction and of the analysis of the radio observations, with particular care to the effects of clean bias and bandwidth smearing, and of the methods used to obtain the catalogue of radio sources. To estimate the effect of the resolution bias on our observations we have modelled the effective angular-size distribution of the sources in our sample and we have used this distribution to simulate a sample of radio sources. Finally we present the radio count distribution down to 0.08mJy derived from the catalogue. Our counts are in good agreement with the best fit derived from earlier surveys, and are about 50% higher than the counts in the HDF. The radio count distribution clearly shows, with extremely good statistics, the change in the slope for the sub-mJy radio sources.2003A&A...403..857Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/403/857CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/403/857https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/403/857http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/403/857https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/403/857https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/403/857http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/403/857GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/403/857/catalog (Radio catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/857/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/857/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/857/catalog?GETtext/xml+votable180.050000true36.002375-4.0910.0055555555555555566/17683 17686 17689 17692 17694 178789.276497240453405e-25 9.276497240453405e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/403/857?format=asciiRadiodefaultJ/A+A/403/857/catalogRadio cataloguerecnoRecord number assigned by the VizieR team.
