cds-question@unistra.frgalaxiesphotometryccd-photometrycarbon-starsWe have imaged a 42'x28' field centered on the spheroidal galaxy NGC 147 to study its AGB population and determine the main structural properties of this M31 companion. This field was observed through two broadband (R and I) and two narrowband (CN and TiO) filters, following the standard approach of our systematic survey of C stars in nearby galaxies. We identified 288 C stars in NGC 147. The average I-magnitude of such sample of C stars is <I>=20.31 with {sigma}=0.40. If we adopt a distance modulus {mu}0=24.39, derived from the luminosity of both the tip of the red giant branch (TRGB) and the horizontal branch (HB) by Han et al. (1997, Cat. <J/AJ/113/1001>, we conclude that the average absolute I-magnitude of C stars is <M_I_>=-4.39, thus slightly under luminous with respect to what was found for other galaxies in our survey.2004A&A...418...33Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/418/33CatalogResearchIsServedByTAP 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/A+A/410/795 : Photometry of NGC 3109 carbon stars (Demers+, 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/403/93 : Photometry of AGB stars in NGC 185 and NGC 147 (Nowotny+, 2003)J/A+A/445/69 : JHK' photometry of C stars in NGC 147 (Sohn+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/418/33https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/418/33http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/418/33https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/418/33https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/418/33http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/418/33GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/418/33/table2 (Positions and photometry of 288 C stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/418/33/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/418/33/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/418/33/table2?GETtext/xml+votable180.050000true7.87137548.29111110.0055555555555555566/2777 2779-2780https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/418/33?format=asciiOpticaldefaultJ/A+A/418/33/table2Positions and photometry of 288 C starsrecnoRecord number assigned by the VizieR team.
