It has also been observed in the optical with the Canada-France Hawaii Telescope (CFHTLS survey), and in the infrared with the Spitzer Space Telescope (SWIRE survey). These surveys have been carried out to study the structure and evolution of both baryonic and dark matter on cosmological scales. In two previous papers, we presented deep low frequency radio surveys of the XMM-LSS field, with limiting flux density levels of ~4 and ~1.5mJy/beam at 325 and 610MHz respectively (5{sigma}). These radio surveys were motivated by the need to understand the various connections between the host galaxies of radio sources and their environments. In this paper, we identify optical counterparts to the low frequency radio sources, using the CFHTLS optical catalogue and images, that have an i-band limiting magnitude of i_AB_~25.2008A&A...490..879Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/490/879CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/456/791 : XMM-LSS field at 74 and 325MHz (Tasse+, 2006)J/A+A/471/1105 : XMM-LSS at 240MHz and 610MHz (Tasse+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/490/879https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/490/879http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/490/879https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/490/879https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/490/879http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/490/879GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/490/879/tabled2 (and optical identification)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/490/879/tabled2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/490/879/tabled2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/490/879/tabled2?GETtext/xml+votable180.050000true33.7201667-4.1892750.0055555555555555565/4422 6/17671 17677 17679 17681-17684 17686-17687 17692-17694 17712-177132.483060040379131e-20 5.517906024225661e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/490/879?format=asciiOpticalMillimeterRadiodefaultJ/A+A/490/879/tabled2and optical identificationl_rmagLimit flag on rmagmeta.code.errorcharrecnoRecord number assigned by the VizieR team.
