cds-question@unistra.fropen-star-clustersccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryastronomical-object-identificationWe present new UBVIc CCD photometry of the young open clusters Trumpler 14 (Tr 14) and Trumpler 16 (Tr 16) in the {eta} Carina Nebula (NGC 3372). We also identify the optical counterpart of Chandra X-ray sources and Two Micron All Sky Survey point sources. The members of the clusters were selected from the proper-motion study, spectral types, reddening characteristics, and X-ray or near-IR excess emission. An abnormal reddening law R_V,cl_=4.4+/-0.2 was obtained for the stars in the {eta} Carina Nebula using the 141 early-type stars with high proper-motion membership probability (P_{mu}_>=70%). We determined the distance to each cluster and conclude that Tr 14 and Tr 16 have practically the same distance modulus of V_0_-M_V_=12.3+/-0.2mag (d=2.9+/-0.3kpc). The slope of the initial mass function was determined to be {Gamma}=-1.3+/-0.1 for Tr 14, {Gamma}=-1.3+/-0.1 for Tr 16, and {Gamma}=-1.4+/-0.1 for all members in the observed region for the stars with log m>=0.2. We also estimated the age of the clusters to be about 1-3Myr from the evolutionary stage of evolved stars and low-mass pre-main-sequence stars.2012AJ....143...41Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/ocl : Optically visible open clusters and Candidates (Dias+ 2002-2013)B/chandra : The Chandra Archive Log (CXC, 1999-2013)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/194/9 : X-ray star clusters in the Carina complex (Feigelson+, 2011)J/ApJS/194/10 : NIR properties of YSO in the CCCP (Preibisch+, 2011)J/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/MNRAS/407/2109 : Kinematic study of open clusters (Vande Putte+, 2010)J/A+A/515/A26 : H and Ks photometry of Trumpler 14 (Sana+, 2010)J/other/NewA/15.108 : UBVRIH{alpha} of {eta} Car (Fernandez-Lajus+ 2010)J/A+A/493/1093 : BVRI light curves of {eta} Car (Fernandez-Lajus+, 2009)J/A+A/490/1055 : Tr 16 low-mass stars in Chandra (Albacete-Colombo+, 2008)J/ApJ/667/963 : Near-infrared photometry of Carina nebula (Sanchawala+ 2007)J/A+A/476/199 : Trumpler 14 JHKL' photometry (Ascenso+, 2007)J/MNRAS/367/513 : JHKs[3.5][4.5] photometry of NGC 3372 (Tapia+, 2006)J/A+A/418/525 : Collinder 232 & Tr 14/16 UBVRI photometry (Carraro+, 2004)J/ApJ/549/578 : BV photometry of Trumpler 14 and 16 (Degioia-Eastwood+ 2001)J/A+AS/116/75 : Region of the open cluster Tr 14 (Vazquez+, 1996)J/AJ/105/980 : Stellar content of Tr 14 and Tr 16 (Massey+, 1993)J/AJ/105/258 : UBVRI polarimetry in Car Nebula (Marraco+ 1993)J/AJ/105/1822 : Open clusters near eta Car (Cudworth+, 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/143/41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/143/41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/143/41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/143/41https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/143/41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/143/41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/143/41/table1 (Photometric data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/143/41/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/143/41/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/143/41/table1?GETtext/xml+votable180.050000true160.74-59.7896110.0055555555555555566/380163.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/143/41?format=asciiOpticalInfrareddefaultJ/AJ/143/41/table1Photometric dataU-B?
