cds-question@unistra.frglobular-star-clustersphotometryWhiting 1 is a member of the fast-growing group of young globular clusters in the Milky Way halo. Preliminary estimates of its fundamental parameters have been provided using optical photometry and low-resolution spectroscopy. In an attempt to strengthen our knowledge of Whiting 1, in this study we employ a complementary approach. Isochrone fitting method was applied on the near-infrared colour-magnitude diagram and yields an age t=5.7+/-0.3Gyr, metallicity z=0.006+/-0.001 ([Fe/H]=-0.5+/-0.1) and distance modulus (m-M)0=17.48+/-0.10. Our results confirm that Whiting 1 is a young and moderately metal-rich globular cluster. It is one of the youngest from the Sgr dSph. We fitted an Elson, Fall and Freeman (EFF) profile to the near-infrared number counts, and measured cluster core radius r_c_=9.1+/-3.9". Two probable eclipsing variables in the cluster were found from multi-epoch V-band photometry. Finally, an unknown galaxy cluster was identified on our K versus (J-K) colour-magnitude diagram. It has a redshift z~1, and it is located at about 1arcmin from the centre of Whiting 1 at {alpha}_J2000_= 02:02:56.6, {delta}_J2000_=-03:16:09, contaminating the cluster photometry.2015MNRAS.446..730Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/446/730CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/466/181 : BVI photometry of Whiting 1 (Carraro+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/446/730https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/446/730http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/446/730https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/446/730https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/446/730http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/446/730GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/446/730/table2 (Photometry of the stars in Whiting 1 and the surrounding field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/446/730/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/446/730/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/446/730/table2?GETtext/xml+votable180.050000true30.727625-3.21216670.0055555555555555566/17711https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/446/730?format=asciiOpticaldefaultJ/MNRAS/446/730/table2Photometry of the stars in Whiting 1 and the surrounding fieldrecnoRecord number assigned by the VizieR team.
