Color-magnitude diagrams (CMDs) are constructed and reach well past the main-sequence turnoff for both clusters. Cluster ages are determined by means of isochrone fitting to the cluster CMDs. These fits are constrained to agree with spectroscopic metallicity and reddening estimates. Cluster ages are determined to be 7.0+/-0.5Gyr for NGC 188 and 10.0+/-1.0Gyr for Berkeley 17, where the errors refer to uncertainties in the relative age determinations.2006AJ....131.1565Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/1565CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/483/826 : BVI CCD photometry of Berkeley 17 (Phelps 1997)J/A+A/390/961 : VI photometry in NGC 188 (Andreuzzi+, 2002)J/PASP/116/1012 : A star catalog for the open cluster NGC 188 (Stetson+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/1565https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/1565http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/1565https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/1565https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/1565http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/1565GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/1565/table2 (NGC 188 Photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/1565/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/1565/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/1565/table2?GETtext/xml+votable180.050000true11.016023185.31480030.005555555555555556Cone search capability for table J/AJ/131/1565/table3 (Berkeley 17 photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/1565/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/1565/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/1565/table3?GETtext/xml+votable180.050000true80.0320569430.58126250.0055555555555555566/4078 24491https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/1565?format=asciiOpticalInfrareddefault
