Observations of the two low-luminosity dwarf irregular galaxies, Pegasus and DDO 210, revealed 40 and three C stars, respectively, assuming that the reddening of Pegasus is negligible. No C stars were identified in Tucana. Our observations permit the estimation of the color-magnitude diagram contamination by foreground M dwarfs thus yielding reliable C/M ratios. Our R and I photometry of the C stars cannot be used to solve the extinction controversy toward Pegasus. The three C stars in DDO 210 are quite bright when compared with C star populations in other dwarf galaxies. A larger, fainter population in that galaxy seems improbable, however. The statistics of C stars currently on hand for dwarf galaxies show a well-defined trend with the absolute magnitude of dwarf galaxies.2000AJ....120.1801Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/120/1801CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/119/2780 : C stars in IC 1613 (Albert+, 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/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/AJ/120/1801https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/120/1801http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/120/1801https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/120/1801https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/120/1801http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/120/1801GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/120/1801/table4 (C stars in Pegasus)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/120/1801/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/120/1801/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/120/1801/table4?GETtext/xml+votable180.050000true352.20837514.71347220.005555555555555556Cone search capability for table J/AJ/120/1801/table5 (C stars in DDO 210)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/120/1801/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/120/1801/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/120/1801/table5?GETtext/xml+votable180.050000true311.7102917-12.840.0055555555555555566/19990 48942-48943https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/120/1801?format=asciiOpticaldefaultJ/AJ/120/1801/table4C stars in PegasusrecnoRecord number assigned by the VizieR team.
