cds-question@unistra.fropen-star-clustersvisible-astronomymedium-band-photometryWe have investigated the two open clusters NGC 6192 and NGC 6451 for which widely different reddening values and thus ages and distances via Stroemgren uvby photometry can be found in the literature. Our measurements allow us to disentangle the apparent discrepancies in the literature and to derive new accurate values. From appropriate calibrations we find that the overall abundance for NGC 6192 is about solar whereas a subsolar value for NGC 6451 was estimated. From two previous reported photometrically candidate CP stars, one within NGC 6192 shows Stroemgren indices typical for a B8Si star whereas the other object of NGC 6451 is most probably a foreground G-type star.2003A&A...403..937Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/403/937CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/116/263 : VI photometry of open clusters (Piatti+, 1998)J/A+A/385/867 : CCD {Delta}a-photometry of 5 open clusters (Paunzen+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/403/937https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/403/937http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/403/937https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/403/937https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/403/937http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/403/937GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/403/937/table3 (Observed program stars of NGC 6192)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/937/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/937/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/937/table3?GETtext/xml+votable180.050000true249.955666-43.4784390.005555555555555556Cone search capability for table J/A+A/403/937/stars (NGC 6192 star positions (from Simbad), for stars with WEBDA number)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/937/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/937/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/937/stars?GETtext/xml+votable180.050000true250.150417-43.3705560.005555555555555556Cone search capability for table J/A+A/403/937/table4 (Observed program stars of NGC 6451)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/937/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/937/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/937/table4?GETtext/xml+votable180.050000true267.587675-30.34320250.0055555555555555566/28822 42402https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/403/937?format=asciiOpticaldefaultJ/A+A/403/937/table3Observed program stars of NGC 6192e_m1Sigma m1magstat.errorfloatrecnoRecord number assigned by the VizieR team.
