cds-question@unistra.frvisible-astronomymedium-band-photometryWe have initiated a faint photometric survey in the Stroemgren system covering ~1 square degree and including 1238 objects in order to develop samples which best probe the thick disk population. The catalog of observations are presented here. They were acquired without kinematic or metallicity biases and are complete to V=17.3-18.5, depending on the field, for 810 early to relatively late type (K0 V or G5 III) stars. Photometric metallicities were derived for 508 stars and indicate a metal-poor stellar population, consistent with a mixture of thick disk and halo stars. While the Stroemgren u-band was not part of the survey, follow-up u-band observations of 32 survey objects indicate that intermediate color survey stars (0.3<=b-y<=0.5) are main-sequence or slightly evolved stars, while redder survey stars (b-y>=0.5) are giants. The survey catalog is available in electronic form upon request.1992AJ....104.1765Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/104/1765CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/104/1765https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/104/1765http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/104/1765https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/104/1765https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/104/1765http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/104/1765GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/104/1765/table4 (Stroemgren survey photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/104/1765/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/104/1765/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/104/1765/table4?GETtext/xml+votable180.050000true12.1130275.437530.0055555555555555566/4566 5065 5068 5816 9456 9458 9751 9757 10380 10382 17790 18139 19097 19100 23465 23468 23476-23478 28559 28570 28581https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/104/1765?format=asciiOpticaldefaultJ/AJ/104/1765/table4Stroemgren survey photometryrecnoRecord number assigned by the VizieR team.
