cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometrytwo-color-diagramsWe present UBVRI photometry of 8702 stars in a 0.5x0.5{deg} field in the direction of NGC7142, taken with the Half Degree Imager at the WIYN 0.9m telescope, to improve knowledge of this cluster's basic parameters. Our photometry spans the ranges 10.6-20.4mag in U, 10.6-22.0mag in B, 10.0-21.8mag in V, 9.2-20.7mag in R, and 8.5-19.9mag in I. Using color-color diagrams that employ all four color combinations that include U, versus B-V, we derive a reddening-metallicity relation for the cluster, with preferred values E(B-V)=0.338{+/-}0.031mag for the left-edge fiducial of the main sequence and [Fe/H]=0.0{+/-}0.1dex, where the Hyades cluster has been used as an unreddened reference cluster, the extinction relations of Cardelli have been employed, and the metallicity dependence of the Yonsei-Yale (Y^2^) isochrones has been assumed. Comparison of our data to the Y^2^ isochrones in multiple color-magnitude diagrams (CMDs) yields distance-metallicity and age-metallicity relations, with preferred values of m-M=12.65{+/-}0.23 mag and age=4.0_+1.3_^-0.7^Gyr. Re-evaluation of the parameters of M67 using Stetson's UBVI photometry yields [Fe/H]=-0.02{+/-}0.05dex, E(B-V)=0.04{+/-}0.01mag, m-M=9.75{+/-}0.03mag, and age=3.85{+/-}0.17Gyr; we thus find the metallicity and age of the two clusters to be indistinguishable. A semi-independent analysis adopting the parameters of M67 and shifting the fiducials of the two clusters in six CMDs until they match strongly corroborates the values listed above. The differences between our inferred parallaxes and the Gaia DR2 values are 87{+/-}60{mu}as for NGC7142 and 48{+/-}15{mu}as for M67, consistent with previous studies.2020AJ....159..246Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/246CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/118/2894 : UBVRI CCD photometry in NGC 188 (Sarajedini+, 1999)J/AJ/122/1486 : NGC 2451A proper motions and membership (Platais+, 2001)J/AJ/124/601 : Absolute positions & proper motions in NGC 188 (Platais+, 2002)J/AJ/126/2922 : Astrometry and membership in NGC 188 (Platais+, 2003)J/A+A/461/509 : Membership and spectroscopy of IC 2391 (Platais+, 2007)J/AJ/134/1216 : Abundances of NGC 7142, 6939, & IC 4756 stars (Jacobson+, 2007)J/AJ/135/2264 : Stellar radial velocities in NGC 188 (Geller+, 2008)J/AJ/137/3743 : Spectroscopic binary orbits in NGC 188 (Geller+, 2009)J/AJ/138/159 : NGC 6819 stellar radial-velocity and photometry (Hole+, 2009)J/AJ/139/1383 : Radial velocities in M35 (NGC 2168) (Geller+, 2010)J/AJ/139/2034 : NGC 6253 stars equivalent widths (Anthony-Twarog+, 2010)J/AJ/146/43 : WIYN open cluster study.
