cds-question@unistra.frphotometric-standard-starsvisible-astronomymedium-band-photometryAccurate standard uvby indices are presented for 73 southern B, A, F and G stars in the V magnitude range 8.2 to 10.9. They cover all three transformation regions of the uvby system (Olsen 1983A&AS...54...55O) well. Standard {beta} indices are included for the 55 B, A, and F stars in the sample. Our results provide a useful set of secondary standards for uvby {beta} CCD photometry with southern hemisphere 1-2m class telescopes. A critical comparison with published photometry, in general based on fewer observations, is given.1997A&AS..122..559Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/122/559CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/122/559https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/122/559http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/122/559https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/122/559https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/122/559http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/122/559GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/122/559/table3Catalogue of transformed uvby indices for the observed primary standard stars.c1c1 color indexmagphot.colorfloatrecnoRecord number assigned by the VizieR team.
