cds-question@unistra.frsurveysquasarsinfrared-photometryWe have carried out a survey of the Lockman Hole covering over 24deg^2^ using the Two Micron All Sky Survey (2MASS) observing system in a special mode that reaches roughly 1mag deeper than the nominal 2MASS survey. The resultant point-source catalog reaches to approximately (J, H, Ks)<(17.8, 16.5, 16.0)mag with completeness and reliability in excess of 90%-95% at the faintest levels. These data will be useful in identifying sources in SIRTF surveys of this area. We have cataloged 69,115 objects, almost twice as many as in the nominal 2MASS survey of this region. The sample includes a large number of potential new active galaxies, as well as a T dwarf candidate.2003AJ....125.2521Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/125/2521CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/125/2521https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/125/2521http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/125/2521https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/125/2521https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/125/2521http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/125/2521GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/125/2521/table6 (Lockman Hole Point-Source Data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/125/2521/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/125/2521/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/125/2521/table6?GETtext/xml+votable180.050000true157.5696253.852553890.0055555555555555564/379 5/1509-1511 1528 6/5951 5994 6031 6035 6053 6080 6082 6088 6090 6120-6122 7441 7443-7446https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/125/2521?format=asciiInfrareddefaultJ/AJ/125/2521/table6Lockman Hole Point-Source DatarecnoRecord number assigned by the VizieR team.
