cds-question@unistra.frgalaxiesphotometryccd-photometrycarbon-starsWe present wide field CFH12K observations of the highly reddened Local Group galaxy IC 10. Using R,I,CN and TiO filters we identify 676 carbon stars in the field of IC 10. After mapping the reddening in the field, from the colours of the G dwarfs seen along the line of sight, we determine the mean apparent magnitude of the C star population to be <I_0_>=19.78, leading to a true modulus of (m-M)_0_=24.35+/-0.11 (741+/-37kpc). The old red giant stars define an asymmetric halo. With a halo diameter of at least 30', IC 10 is among the largest dwarfs of the Local Group. The surface density of C stars follows a radial power law with a scale length of 2.36', a value nearly identical to the scale length defined by the old giants thus IC 10 has a stellar halo where the old and intermediate-age populations are well mixed.2004A&A...424..125Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/424/125CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/119/2780 : C stars in IC 1613 (Albert+, 2000)J/AJ/120/1801 : C stars in Pegasus, DDO 210 and Tucana (Battinelli+, 2000)J/AJ/123/832 : C star population in NGC 6822 (Letarte+, 2002)J/AJ/125/1298 : C star population in outer disk of M31 (Battinelli+, 2003)J/AJ/125/3037 : RI photometry of NGC 205 carbon stars (Demers+, 2003)J/A+A/410/795 : Photometry of NGC 3109 carbon stars (Demers+, 2003)J/A+A/418/33 : RI photometry of C stars in NGC 147 (Battinelli+, 2004)J/A+A/417/479 : RI photometry of NGC 185 carbon stars (Battinelli+, 2004)J/A+A/416/111 : C stars in Wolf-Lundmark-Melotte galaxy (Battinelli+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/424/125https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/424/125http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/424/125https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/424/125https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/424/125http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/424/125GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/424/125/table2 (Positions and photometry of 676 C stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/424/125/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/424/125/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/424/125/table2?GETtext/xml+votable180.050000true4.6107559.3310.0055555555555555566/3042-3043https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/424/125?format=asciiOpticaldefaultJ/A+A/424/125/table2Positions and photometry of 676 C starsrecnoRecord number assigned by the VizieR team.
