cds-question@unistra.frinterstellar-mediumextinctioninfrared-sourcesWe extract J and Ks magnitudes from the 2MASS Point Source Catalog for approximately 6 million stars with 8<Ks<13 in order to build an A_K_ extinction map within 10 degrees of the Galactic centre. The extinction was determined by fitting the upper giant branch of (Ks, J-Ks) colour-magnitude diagrams to a dereddened upper giant branch mean locus built from previously studied Bulge fields. The extinction values vary from A_K=0.05 in the edges of the map up to A_K=3.2 close to the Galactic centre. The resulting extinction map is given in the file 'extmap.dat'.2003MNRAS.338..253Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/338/253CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/2mass : The 2MASS database (IPAC/UMass, 2000)II/62 : Catalogue of Extinction Data (Neckel+, 1980)II/114 : UV Interstellar Extinction (Savage+ 1985)J/A+A/349/L69 : Interstellar extinction towards inner Galactic BulgeJ/A+A/359/347 : Reddening in open and globular clusters (Dutra+, 2000)J/A+A/383/631 : Catalogue of dust clouds in the Galaxy (Dutra+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/338/253https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/338/253http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/338/253https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/338/253https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/338/253http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/338/253GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/338/253/extmap (Extinction map (181 x 181 points))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/338/253/extmap?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/338/253/extmap?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/338/253/extmap?GETtext/xml+votable180.050000true268.92562-37.147210.0055555555555555563/450 4/1795 1804 1806 5/7177 7179 7194-7195 7198 7220 7222 7296-7297 7300-7301 7312-7313 10623 10709 6/28686-28687 28705 28707 28713-28715 28768 28770-28771 28774-28775 28786 28796 28798 28912 28914 28920 29209 29212-29213 29256-29257 29260-29262 42461 42463 42485-42487https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/338/253?format=asciiInfrareddefaultJ/MNRAS/338/253/extmapExtinction map (181 x 181 points)recnoRecord number assigned by the VizieR team.
