cds-question@unistra.frearly-type-starsinfrared-sourcesinfrared-photometryThe nuclear star cluster of the Galaxy is an important template for understanding its extragalactic counterparts, which can currently not be resolved into individual stars. Important drawbacks of observations of the Galactic center are, however, the presence of strong and spatially highly variable interstellar extinction and extreme crowding of the sources, which makes the use of adaptive optics techniques necessary. Both points pose serious obstacles to precise photometry that is needed for analyzing the stellar population. The aims of this work are to provide accurate photometry in multiple near-infrared broadband filters, to determine the power-law index of the extinction-law toward the central parsec of the Galaxy, to provide measurements of the absolute extinction toward the Galactic center, and finally to measure the spatial variability of extinction on arcsecond scales.2010A&A...511A..18Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/511/A18CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/433/117 : L- + M-band imaging of the Galactic Center (Viehmann+, 2005)J/ApJ/642/861 : N-band imaging of the Galactic Center (Viehmann+, 2006)J/A+A/499/483 : Sources in galactic center NIR observations (Buchholz+, 2009)J/A+A/502/91 : Proper motions of stars near SgrA* (Schoedel+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/511/A18https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/511/A18http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/511/A18https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/511/A18https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/511/A18http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/511/A18GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/511/A18/tablea2 (Stellar positions and magnitudes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/511/A18/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/511/A18/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/511/A18/tablea2?GETtext/xml+votable180.050000true266.4168403-29.00781890.0055555555555555566/288304.925240337479573e-20 1.2934455535160846e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/511/A18?format=asciiInfrareddefaultJ/A+A/511/A18/tablea2Stellar positions and magnitudesSeqSequential numbermeta.recordintrecnoRecord number assigned by the VizieR team.
