cds-question@unistra.frsurveysgalaxiescatalogsredshiftedThis paper describes the first data release (DR1) of the VIMOS Ultra Deep Survey (VUDS). The VUDS-DR1 is the release of all low-resolution spectroscopic data obtained in 276.9 arcmin^2^ of the CANDELS-COSMOS and CANDELS-ECDFS survey areas, including accurate spectroscopic redshifts z_spec_ and individual spectra obtained with VIMOS on the ESO-VLT. A total of 698 objects have a measured redshift, with 677 galaxies, two type-I AGN, and a small number of 19 contaminating stars. The targets of the spectroscopic survey are selected primarily on the basis of their photometric redshifts to ensure a broad population coverage. About 500 galaxies have z_spec_>2, 48of which have z_spec_>4; the highest reliable redshifts reach beyond z_spec_=6. This data set approximately doubles the number of galaxies with spectroscopic redshifts at z>3 in these fields. We discuss the general properties of the VUDS-DR1 sample in terms of the spectroscopic redshift distribution, the distribution of Lyman-{alpha} equivalent widths, and physical properties including stellar masses M* and star formation rates derived from spectral energy distribution fitting with the knowledge of z_spec_. We highlight the properties of the most massive star-forming galaxies, noting the wide range in spectral properties, with Lyman-{alpha} in emission or in absorption, and in imaging properties with compact, multi-component, or pair morphologies. We present the catalogue database and data products. All VUDS-DR1 data are publicly available and can be retrieved from a dedicated query-based database. Future VUDS data releases will follow this VUDS-DR1 to give access to the spectra and associated measurement of ~8000 objects in the full ~1 square degree of the VUDS survey.2017A&A...600A.110Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/600/A110CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://cesam.lam.fr/vuds/DR1 : VUDS-DR1 home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/600/A110https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/600/A110http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/600/A110https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/600/A110https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/600/A110http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/600/A110GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/600/A110/cosmos (VUDS-DR1 COSMOS field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/600/A110/cosmos?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/600/A110/cosmos?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/600/A110/cosmos?GETtext/xml+votable180.050000true150.146102912.552927020.005555555555555556Cone search capability for table J/A+A/600/A110/ecdfs (VUDS-DR1 ECDFS field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/600/A110/ecdfs?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/600/A110/ecdfs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/600/A110/ecdfs?GETtext/xml+votable180.050000true53.17780685-27.757795330.0055555555555555566/27258 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/600/A110?format=asciidefaultJ/A+A/600/A110/cosmosVUDS-DR1 COSMOS fieldslit[1/128] Slit numbermeta.noteintrecnoRecord number assigned by the VizieR team.
