cds-question@unistra.frinfrared-photometrygalaxiesinfrared-sourcesDeep near-infrared (NIR) J- and K-band photometry of three Local Group dwarf spheroidal galaxies-Fornax, Carina, and Sculptor-is made available for the community. Until now, these data have only been used by the Araucaria Project to determine distances using the tip of the red giant branch and RR Lyrae stars. Now, we present the entire data collection in the form of a database, consisting of accurate J- and K-band magnitudes, sky coordinates, ellipticity measurements, and timestamps of observations, complemented by stars' loci in their reference images. The depth of our photometry reaches about 22 mag at the 5{sigma} level, and is comparable to NIR surveys, such as the UKIRT Infrared Deep Sky Survey (UKIDSS) or the VISTA Hemisphere Survey (VHS). Small overlap with VHS and no overlap with UKIDSS makes our database a unique source of quality photometry.2021ApJS..253...42Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/253/42CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/eso : ESO Science Archive Catalog (ESO, 1991-2021)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/359 : The VISTA Hemisphere Survey (VHS) catalog DR4.1 (McMahon+, 2013)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/AJ/135/1993 : JHK magnitudes of Sculptor RR Lyrae (Pietrzynski+, 2008)J/AJ/138/1661 : The Araucaria Project: RR Lyrae in SMC (Szewczyk+, 2009)J/ApJ/780/59 : The Araucaria project: EBs in SMC (Graczyk+, 2014)J/AJ/154/263 : NIR photometry of 77 RR Lyrae stars (Karczmarek+, 2017)http://araucaria.camk.edu.pl/ : Araucaria project home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/253/42https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/253/42http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/253/42https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/253/42https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/253/42http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/253/42GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/253/42/table4 (Journal of observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/253/42/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/253/42/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/253/42/table4?GETtext/xml+votable180.050000true100.362083-50.9758330.005555555555555556Cone search capability for table J/ApJS/253/42/carina (Carina database)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/253/42/carina?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/253/42/carina?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/253/42/carina?GETtext/xml+votable180.050000true100.21375611-51.029163890.005555555555555556Cone search capability for table J/ApJS/253/42/fornax (Fornax database)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/253/42/fornax?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/253/42/fornax?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/253/42/fornax?GETtext/xml+votable180.050000true40.132415-34.465391940.005555555555555556Cone search capability for table J/ApJS/253/42/sculptor (Sculptor database)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/253/42/sculptor?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/253/42/sculptor?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/253/42/sculptor?GETtext/xml+votable180.050000true15.01177611-33.717828060.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/ApJS/253/426/35549 35720 35969 39094 39097 39100https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/253/42?format=asciiInfrareddefaultJ/ApJS/253/42/table4Journal of observationsNsNumber of stars in this fieldmeta.numberintnullableDateDate of observation (UT)time.epochnullableInstInstrument ("HAWK-I", "SOFI" or "ISAAC")meta.id;instrcharrecnoRecord number assigned by the VizieR team.
