cds-question@unistra.frmagellanic-cloudsstellar-associationsvisible-astronomysloan-photometryWe present Gemini South GMOS g, i photometry of 14 intermediate-age Large Magellanic Cloud (LMC) star clusters, namely: NGC 2155, 2161, 2162, 2173, 2203, 2209, 2213, 2231, 2249, Hodge 6, SL 244, 505, 674, and 769, as part of a continuing project to investigate the extended main-sequence turn-off (EMSTO) phenomenon. Extensive artificial star tests were made over the observed field of view. These tests reveal the observed behaviour of photometric errors with magnitude and crowding. The cluster stellar density radial profiles were traced from star counts over the extent of the observed field. We adopt cluster radii and build colour-magnitude diagrams (CMDs) with cluster features clearly identified. We used the cluster (g, g-i) CMDs to estimate ages from the matching of theoretical isochrones. The studied LMC clusters are confirmed to be intermediate-age clusters, which range in age 9.10<log(t)<9.60. NGC 2162 and NGC 2249 look like new EMSTO candidates, in addition to NGC 2209, on the basis of having dual red clumps.2014MNRAS.444.1425Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/444/1425CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/444/1425https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/444/1425http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/444/1425https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/444/1425https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/444/1425http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/444/1425GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/444/1425/table1 (Observation log of selected clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/444/1425/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/444/1425/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/444/1425/table1?GETtext/xml+votable180.050000true89.6375-65.476940.005555555555555556Cone search capability for table J/MNRAS/444/1425/stars (CCD gi data of stars in the field of the 14 observed LMC clusters (tables 2--15))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/444/1425/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/444/1425/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/444/1425/stars?GETtext/xml+votable180.050000true89.55342083-65.524163890.0055555555555555566/33041 33044-33045 33047 33052 33092 33110 33120-33121 33793 33797 37386 37410 37504 37516 37537 38922https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/444/1425?format=asciiOpticaldefaultJ/MNRAS/444/1425/table1Observation log of selected clustersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
