cds-question@unistra.frmolecular-cloudsccd-photometryinfrared-photometryWe present a deep optical/near-infrared imaging survey of the Serpens molecular cloud. This survey constitutes the complementary optical data to the Spitzer "Core To Disk" (c2d) Legacy survey in this cloud. The survey was conducted using the Wide Field Camera at the Isaac Newton Telescope. About 0.96 square degrees were imaged in the R and Z filters, covering the entire region where most of the young stellar objects identified by the c2d survey are located. 26524 point-like sources were detected in both R and Z bands down to R=24.5mag and Z=23mag with a signal-to-noise ratio better than 3. The 95% completeness limit of our catalog corresponds to 0.04 solar masses for members of the Serpens star forming region (age 2Myr and distance 260pc) in the absence of extinction. Adopting the typical extinction of the observed area (Av=7mag), we estimate a 95% completeness level down to 0.1 solar masses. The astrometric accuracy of our catalog is 0.4-arcsec with respect to the 2MASS catalog. Our final catalog contains J2000 celestial coordinates, magnitudes in the R and Z bands calibrated to the SDSS photometric system and, where possible, JHK magnitudes from 2MASS for sources in 0.96 square degrees in the direction of Serpens. This data product has been already used within the frame of the c2d Spitzer Legacy Project analysis in Serpens to study the star/disk formation and evolution in this cloud; here we use it to obtain new indications of the disk-less population in Serpens.2010A&A...513A..38Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/513/A38CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/A+A/330/990 : VRIJHK photometry of Serpens cloud core (Giovannetti+ 1998)J/A+A/421/623 : ISOCAM survey of YSOs in Serpens Cloud Core (Kaas+, 2004)J/A+A/425/927 : Stellar objects in the Serpens cloud field (Klotz+, 2004)J/ApJ/663/1149 : Spitzer survey of Serpens YSO population (Harvey+, 2007)J/ApJ/669/493 : Spitzer/Chandra YSOs in Serpens cloud core (Winston+, 2007)J/A+A/463/275 : Chandra obs. of Serpens star-forming region (Giardino+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/513/A38https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/513/A38http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/513/A38https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/513/A38https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/513/A38http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/513/A38GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/513/A38/catalog (Photometric catalog for 28995 stellar sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/513/A38/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/513/A38/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/513/A38/catalog?GETtext/xml+votable180.050000true276.896367220.134459170.0055555555555555565/7590 6/303668.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/513/A38?format=asciiInfrareddefaultJ/A+A/513/A38/catalogPhotometric catalog for 28995 stellar sourcesrecnoRecord number assigned by the VizieR team.
