The I magnitude of the tip of the Red Giant Branch is robustly estimated from two different datasets I^TRGB^=17.97 (^+0.05^_-0.03_). From this estimate, adopting [M/H]~-1.2 from the comparison of RGB stars with Galactic templates, we obtain a distance modulus (m-M)_0=22.02+/-0.13, corresponding to a distance D=254^+16^_-19_kpc.2004MNRAS.354..708Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/354/708CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/354/708https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/354/708http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/354/708https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/354/708https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/354/708http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/354/708GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/354/708/table (Stars positions and magnitudes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/354/708/table?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/354/708/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/354/708/table?GETtext/xml+votable180.050000true152.1274166712.355981110.0055555555555555566/27574 27580https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/354/708?format=asciiOpticalInfrareddefaultJ/MNRAS/354/708/tableStars positions and magnitudesSeqIdentification numberintrecnoRecord number assigned by the VizieR team.
