cds-question@unistra.frgalaxiesphotometrycarbon-starsccd-photometryWe present a CFH12K wide field survey of the carbon star population in and around NGC 3109. Carbon stars, the brightest members of the intermediate-age population, were found nearly exclusively in and near the disk of NGC 3109, ruling out the existence of an extensive intermediate-age halo like the one found in NGC 6822. Over 400 carbon stars identified have M_I_=-4.71, confirming the nearly universality of mean magnitude of C star populations in Local Group galaxies. Star counts over the field reveal that NGC 3109 is a truncated disk shaped galaxy without an extensive stellar halo. The minor axis star counts reach the foreground density between 4' and 5', a distance that can be explained by an inclined disk rather than a spheroidal halo. We calculate a global C/M ratio of 1.75+/-0.20, a value expected for such a metal poor galaxy.2003A&A...410..795Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/410/795CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/119/2780 : C star in 1613 (Albert+, 2003)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/416/111 : C stars in Wolf-Lundmark-Melotte galaxy (Battinelli+, 2004)J/A+A/417/479 : RI photometry of NGC 185 carbon stars (Battinelli+, 2004)J/A+A/418/33 : RI photometry of C stars in NGC 147 (Battinelli+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/410/795https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/410/795http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/410/795https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/410/795https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/410/795http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/410/795GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/410/795/table2 (Positions and photometry of 471 C stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/410/795/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/410/795/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/410/795/table2?GETtext/xml+votable180.050000true150.3854167-26.25291670.0055555555555555566/38843 38846https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/410/795?format=asciiOpticaldefaultJ/A+A/410/795/table2Positions and photometry of 471 C starsrecnoRecord number assigned by the VizieR team.
