cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryproper-motionsOptical UBVRI photometric measurements using the Faulkes Telescope North were taken in early 2011 and combined with 2MASS JHK_s_ and WISE infrared photometry as well as UCAC4 proper motion data in order to estimate the main parameters of the galactic open cluster NGC 2215 of which large uncertainty exists in the current literature. Fitting a King model we estimate a core radius of 1.12'+/-0.04'(0.24+/-0.01pc) and a limiting radius of 4.3'+/-0.5'(0.94+/-0.11pc) for the cluster. The results of isochrone fits indicates an age of log(t)=8.85+/-0.10 with a distance of d=790+/-90pc, a metallicity of [Fe/H]=-0.40+/-0.10dex, and a reddening of E(B-V)=0.26+/-0.04. A proportion of the work in this study was undertaken by Australian and Canadian upper secondary school students involved in the Space to Grow astronomy education project, and is the first scientific publication to have utilized our star cluster photometry curriculum materials.2015AJ....149..190Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/149/190CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/ocl : Optically visible open clusters and Candidates (Dias+ 2002-2014)II/328 : AllWISE Data Release (Cutri+ 2013)II/311 : WISE All-Sky Data Release (Cutri+ 2012)I/322 : UCAC4 Catalogue (Zacharias+, 2012)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/146/88 : UBVRI standard stars around celestial equator (Clem+, 2013)J/A+A/446/949 : Open clusters proper motions based on UCAC2 (Dias+, 2006)J/A+A/438/1163 : Catalogue of Open Cluster Data (COCD) (Kharchenko+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/149/190https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/149/190http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/149/190https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/149/190https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/149/190http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/149/190GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/149/190/table3 (Astrometry and photometry of the stars, combined with 2MASS and WISE.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/149/190/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/149/190/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/149/190/table3?GETtext/xml+votable180.050000true95.13074806-7.305290.0055555555555555566/213693.830199579824256e-20 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/149/190?format=asciiOpticalInfrareddefaultJ/AJ/149/190/table3Astrometry and photometry of the stars, combined with 2MASS and WISE.Bmag[11.4/21.6]?
