cds-question@unistra.frinfrared-photometryvisible-astronomybroad-band-photometrystandard-starsHigh-quality CCD-based UBVRI photometry is presented for ~45000 stars distributed among 60 different fields centered on the celestial equator and at {delta}{approx}-50{deg}. This photometry has been calibrated to the standard Johnson UBV and Kron-Cousins RI systems via observations of the UBVRI standard stars presented in the works of Landolt. The majority of the stars in our photometric catalog fall in the magnitude range 12<~V<~22 and in the color range -0.3<~(B-V)<~1.8. Each star averages 67 measures in each UBVRI filter from data taken on 250 different photometric nights over a period of ~6.5yr from two different telescopes. Our final photometric database effectively extends the UBVRI standard star network defined by Landolt to much fainter magnitudes and increases the number density of stars within pre-existing standard fields. Hence, these new, fainter standards serve as suitable calibrators for investigators who employ either small or large-aperture telescopes for their observational projects.2013AJ....146...88Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/146/88CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/183 : UBVRI Photometric Standards (Landolt 1992)J/AJ/137/4186 : UBVRI standards around celestial equator (Landolt, 2009)J/AJ/133/768 : KPNO's UBVRI filter transmission characteristicsJ/AJ/133/2502 : UBVRI Standard Stars (Landolt, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/146/88https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/146/88http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/146/88https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/146/88https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/146/88http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/146/88GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/146/88/table7 (UBVRI photometry and astrometry for stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/146/88/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/146/88/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/146/88/table7?GETtext/xml+votable180.050000true38.64483333.80569440.0055555555555555565/8844 9581 11229 6/17790 17877 17879 18087 19027 19033 19050 19051 19089 19091 19094 19120 19122 19137 19138 19141 19144 19970 21756 21828 21829 21831 21864 21865 21866 22100 22120 22121 22883 22884 22886 23101 23103 23145 23186 23187 23190 23191 23240 23789 23800 25751 25794 25915 25918 25945 26001 26175 26208 26210 26219 26261 26808 26810 26916 26918 27045 27047 27056 27058 27187 27235 27238 27321 27324 30357 30400 31144 31146 31147 31315 31321 31324 31381 31382 31424 31557 31559 31593 31594 31595 33946 33947 33968 33969 34034 34035 34067 34407 34418 34424 35339 35361 37786 37808 38164 38165 39319 39362 42129 43305 45267 45270 45349 45360 47458 49031 49042 490482.367228618189496e-19 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/146/88?format=asciiOpticalInfrareddefaultJ/AJ/146/88/table7UBVRI photometry and astrometry for starse_UmagUncertainty in Umagmagstat.error;phot.mag;em.opt.UfloatrecnoRecord number assigned by the VizieR team.
