cds-question@unistra.frstandard-starsinfrared-photometryvisible-astronomybroad-band-photometryoptical-observationcatalogsUBVRI photoelectric observations have been made of 109 stars around the sky, centered more or less at -50{deg} declination. The majority of the stars fall in the magnitude range 10.4<V<15.5 and in the color index range -0.33<(B-V)<+1.66. These new broadband photometric standard stars average 16.4 measurements each from data taken on 116 different nights over a period of 4yr. Similar data are tabulated for 19 stars of interest that were not observed often enough to make them well-defined standard stars.2007AJ....133.2502Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/2502CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/118 : UBVRI standards around Celestial Equator (Landolt 1983)II/183 : UBVRI Photometric Standards (Landolt 1992)I/277 : SPM Catalog 2.0 (Platais+ 1998)III/137 : Spectroscopically Identified Hot SubdwarfI/284 : The USNO-B1.0 Catalog (Monet+ 2003)I/289 : UCAC2 Catalogue (Zacharias+ 2004)J/A+A/461/509 : Membership and spectroscopy of IC 2391 (Platais+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/2502https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/2502http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/2502https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/2502https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/2502http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/2502GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/133/2502/phot (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/2502/phot?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/2502/phot?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/2502/phot?GETtext/xml+votable180.050000true2.60366667-50.232111110.005555555555555556Cone search capability for table J/AJ/133/2502/table5 (Accurate Coordinates and Proper Motions for the Stars in Tables 1 and 4)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/2502/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/2502/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/2502/table5?GETtext/xml+votable180.050000true2.60366667-50.232111110.0055555555555555566/33946 33947 33968 34035 34067 34418 34926 34933 34963 35079 35339 35355 35378 35379 35460 35715 37706 37808 38164 38324 38325 38411 38449 38536 39319 39362 40623 42129 42691 43305 43310 45235 45270 45349 46295 47105 47304 47458https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/133/2502?format=asciiOpticalInfrareddefaultJ/AJ/133/2502/photCombined table from original tablesrecnoRecord number assigned by the VizieR team.
