cds-question@unistra.fropen-star-clustersvilnius-photometryThe results of medium-band photometry of 1037 stars in the area of the old open cluster NGC 7142 down to V=20.1mag in the Vilnius seven-colour system are presented. Photometric results are used to classify in spectral and luminosity classes about 80 per cent of stars down to V=18.5mag, to identify cluster members, to determine the main cluster parameters and to investigate the interstellar extinction in this direction. The average extinction A_V_ of the cluster is about 1.1mag [E(B-V)=0.35], and its distance is 2.3kpc (the distance modulus 11.8mag). The age of the cluster, 3.0Gyr, is estimated from the intrinsic colour-magnitude diagram with individual dereddening of each star and the Padova isochrones. The surface distribution of the extinction is shown. The reddening of the eclipsing variable V375 Cep is found to be close to the average reddening of the cluster. Probably, the cluster contains five red clump giants, two asymptotic branch stars and four blue stragglers.2014MNRAS.437.1628Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/437/1628CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASP/103/536 : CCD Photometry of NGC 7142 (Crinklaw+ 1991)J/AJ/134/1216 : NGC 7142, 6939 & IC 4756 stars abundances (Jacobson+, 2007)J/BaltA/21/465 : Vilnius photometry in NGC7129 & NGC7142 (Maskoliunas+, 2012)J/MNRAS/438/1848 : NGC 7129 Vilnius photometry (Straizys+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/437/1628https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/437/1628http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/437/1628https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/437/1628https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/437/1628http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/437/1628GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/437/1628/table2 (Results of photometry and classification of stars in the NGC 7142 area measured in the Vilnius 7-colour system)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/437/1628/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/437/1628/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/437/1628/table2?GETtext/xml+votable180.050000true325.99062565.78463890.0055555555555555566/157593.561607812030676e-19 3.741500294832266e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/437/1628?format=asciiOpticaldefaultJ/MNRAS/437/1628/table2Results of photometry and classification of stars in the NGC 7142 area measured in the Vilnius 7-colour systemU-V?
