A young age of 3.2Gyr is found, differently from a previous estimate of 12Gyr. It also appears to be moderately metal rich with [Fe/H]~-0.8, rather than [Fe/H]~-1.7, as previously suggested by Fadely et al. (2011AJ....142...88F, Cat. J/AJ/142/88). A main difference in the age derivation relative to Fadely et al. comes from the consideration of subgiant branch stars in the isochrone fitting. A deduced distance of d_{sun}_=29.1kpc is compatible with the outer halo location of other low luminosity globular clusters.2013MNRAS.433.1966Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/433/1966CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/142/88 : Segue 3 photometric and kinematic data (Fadely+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/433/1966https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/433/1966http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/433/1966https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/433/1966https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/433/1966http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/433/1966GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/433/1966/seg3viac (Segue 3 V and I photometry (long exposure))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/433/1966/seg3viac?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/433/1966/seg3viac?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/433/1966/seg3viac?GETtext/xml+votable180.050000true320.368295619.05283060.005555555555555556Cone search capability for table J/MNRAS/433/1966/seg3vibc (Segue 3 V and I photometry (short exposure))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/433/1966/seg3vibc?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/433/1966/seg3vibc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/433/1966/seg3vibc?GETtext/xml+votable180.050000true320.314357519.05776530.0055555555555555566/12687 127093.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/433/1966?format=asciiOpticalInfrareddefaultJ/MNRAS/433/1966/seg3viacSegue 3 V and I photometry (long exposure)Seq[1/1248] Sequential number within the tablemeta.recordintprimaryXpos[0/2009] X position (LAB002_A)pos.cartesian.x;instr.detfloatYpos[0/2009] Y position (LAB003_A)pos.cartesian.y;instr.detfloatV-IJohnson-Cousins V-I colour indexmagphot.color;em.opt.V;em.opt.IfloatVmag[20.1/25.9] Johnson V magnitudemagphot.mag;em.opt.Vfloat_RAPosition computed from a comparison with SDSS-DR9 (V/139) ({sigma}=0.10'') (right ascension part)degpos.eq.ra;meta.main_DEPosition computed from a comparison with SDSS-DR9 (V/139) ({sigma}=0.10'') (declination part)degpos.eq.dec;meta.mainJ/MNRAS/433/1966/seg3vibcSegue 3 V and I photometry (short exposure)Seq[4/431] Sequential number within the tablemeta.recordintprimaryXpos[0/2009] X positionpixpos.cartesian.x;instr.detfloatYpos[0/2009] Y positionpixpos.cartesian.y;instr.detfloatV-IJohnson-Cousins V-I colour indexmagphot.color;em.opt.V;em.opt.IfloatVmag[14.4/20.1] Johnson V magnitudemagphot.mag;em.opt.Vfloat_RAPosition computed from a comparison with 2MASS (II/246) ({sigma}=0.11'') (right ascension part)degpos.eq.ra;meta.main_DEPosition computed from a comparison with 2MASS (II/246) ({sigma}=0.11'') (declination part)degpos.eq.dec;meta.main
