cds-question@unistra.frmagellanic-cloudsstellar-associationsvisible-astronomybroad-band-photometryAs part of an ongoing project to investigate the cluster formation and chemical evolution history in the Large Magellanic Cloud (LMC), we have used the CTIO 0.9m telescope to obtain CCD imaging in the Washington system of NGC 2161, SL 874, and KMHK 1719 - three unstudied star clusters located in the outer region of the LMC. We measured T1 magnitudes and C-T1 colors for a total of 9611 stars distributed throughout cluster areas of 13.6x13.6arcmin^2^. Cluster radii were estimated from star counts distributed throughout the entire observed fields. Careful attention was paid to setting apart the cluster and field star distributions so that statistically cleaned color-magnitude diagrams (CMDs) were obtained. Based on the best fits of isochrones computed by the Padova group to the (T1, C-T1) CMDs, the {delta}T1 index, and the standard giant branch procedure, ages and metallicities were derived for the three clusters.2011PASP..123..519Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/123/519CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/123/519https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/123/519http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/123/519https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/123/519https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/123/519http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/123/519GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/123/519/table1 (Observation Log of selected clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/123/519/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/123/519/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/123/519/table1?GETtext/xml+votable180.050000true23.60833-72.874440.005555555555555556Cone search capability for table J/PASP/123/519/table2 (CCD CT1 data of stars in the field of L 110)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/123/519/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/123/519/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/123/519/table2?GETtext/xml+votable180.050000true23.8458458-72.90845280.005555555555555556Cone search capability for table J/PASP/123/519/table3 (CCD CT1 data of stars in the field of L 112)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/123/519/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/123/519/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/123/519/table3?GETtext/xml+votable180.050000true23.6264653-75.39673440.005555555555555556Cone search capability for table J/PASP/123/519/table4 (CCD CT1 data of stars in the field of NGC 2161)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/123/519/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/123/519/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/123/519/table4?GETtext/xml+votable180.050000true89.0138006-74.30015810.005555555555555556Cone search capability for table J/PASP/123/519/table5 (CCD CT1 data of stars in field of SL 874)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/123/519/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/123/519/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/123/519/table5?GETtext/xml+votable180.050000true94.0852514-70.00074360.005555555555555556Cone search capability for table J/PASP/123/519/table6 (CCD CT1 data of stars in field of KMHK 1719)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/123/519/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/123/519/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/123/519/table6?GETtext/xml+votable180.050000true94.0739728-70.00436220.0055555555555555566/32953 33040-33041 33299-33300 33302 37507 375132.9196443747461696e-19 3.2860540898823595e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/123/519?format=asciiOpticaldefaultJ/PASP/123/519/table1Observation Log of selected clustersrecnoRecord number assigned by the VizieR team.
