cds-question@unistra.frradio-sourcesWith the goal of identifying high-redshift radio galaxies with Fanaroff-Riley class I (FR I) classification, here are presented high-resolution, wide-field radio observations, near-infrared and optical imaging and multi-object spectroscopy of two fields of the Leiden-Berkeley Deep Survey. These fields, Hercules.1 and Lynx.2, contain a complete sample of 81 radio sources with S(1.4GHz)>0.5mJy within 0.6deg^2^. This sample will form the basis for a study of the population and cosmic evolution of high-redshift, low-power, FR I radio sources which will be presented in Paper II. Currently, the host galaxy identification fraction is 86 per cent with 11 sources remaining unidentified at a level of r'>=25.2mag (Hercules; 4 sources) or r'>=24.4mag (Lynx; 7 sources) or K>=20mag. Spectroscopic redshifts have been determined for 49 per cent of the sample and photometric redshift estimates are presented for the remainder of the sample.2007MNRAS.380.1449Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/380/1449CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/71/221 : The 65W part of the WSRT 21 cm survey in Lynx (Oort, 1987)J/MNRAS/317/801 : LBDS Hercules sample griJHK photometry (Waddington+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/380/1449https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/380/1449http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/380/1449https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/380/1449https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/380/1449http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/380/1449GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/380/1449/sources (Hercules and Lynx radio source positions from the VLA A-array observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/380/1449/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/380/1449/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/380/1449/sources?GETtext/xml+votable180.050000true259.6422549.98138890.005555555555555556Cone search capability for table J/MNRAS/380/1449/galaxy (Host galaxy positions and magnitudes for Hercules and Lynx fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/380/1449/galaxy?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/380/1449/galaxy?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/380/1449/galaxy?GETtext/xml+votable180.050000true259.641958349.98061110.005555555555555556Cone search capability for table J/MNRAS/380/1449/table11 (Summary of the TNG observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/380/1449/table11?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/380/1449/table11?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/380/1449/table11?GETtext/xml+votable180.050000true131.474083344.71716670.0055555555555555566/6495 6516-6517 9710 10049 10052https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/380/1449?format=asciiRadiodefaultJ/MNRAS/380/1449/sourcesHercules and Lynx radio source positions from the VLA A-array observationsrecnoRecord number assigned by the VizieR team.
