cds-question@unistra.frh-ii-regionsgiant-starsinfrared-photometryA possibility of applying 2MASS J, H, Ks, IPHAS r, i and Mega-Cam u, g photometry of red giants for determining distances to dark clouds is investigated. Red clump giants with a small admixture of G5-K1 and M2-M3 stars of the giant branch can be isolated and used in determining distances to separate clouds or spiral arms. Interstellar extinctions of background red giants can be also used for mapping dust surface density in the cloud.2009BaltA..18..141Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/BaltA/18/141CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/BaltA/15/483 : Vilnius photometry in LDN 935 (Laugalys+, 2006)J/BaltA/17/125 : Interstellar reddening in 3 HII regions (Straizys+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/BaltA/18/141https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/BaltA/18/141http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/BaltA/18/141https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/BaltA/18/141https://vizier.iucaa.in/viz-bin/votable?-source=J/BaltA/18/141http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/BaltA/18/141GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/BaltA/18/141/table2 (Stars in the NAP area with photometric properties of red clump giants in the 2MASS, IPHAS (r, i) and MegaCam (u, g) systems.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/BaltA/18/141/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/BaltA/18/141/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/BaltA/18/141/table2?GETtext/xml+votable180.050000true313.56643.7290.0055555555555555566/14679 15360 15362 15363 15368 153698.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/BaltA/18/141?format=asciiInfrareddefaultJ/BaltA/18/141/table2Stars in the NAP area with photometric properties of red clump giants in the 2MASS, IPHAS (r, i) and MegaCam (u, g) systems.recnoRecord number assigned by the VizieR team.
