cds-question@unistra.frphotometryinfrared-photometryvisible-astronomyWide-band photometryUBVRI photoelectric observations have been made on the Johnson-Kron-Cousins photometric system of 526 stars centered on the celestial equator. The program stars within a 298 number subset have sufficient measures that they are capable of providing, for telescopes of intermediate and large size in both hemispheres, an internally consistent homogeneous broadband standard photometric system around the sky. The stars average 29 measures each on 19 nights. The majority of the stars in this paper fall in the magnitude range 11.5 < V < 16.0, and in the color range -0.3 < (B-V) < +2.3. Note: Tables 6 to 10 (filter sensitivities) were grouped into the "filters" file.1992AJ....104..340Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/183ACatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/183Ahttps://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/183Ahttp://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/183Ahttps://vizier.cds.unistra.fr/viz-bin/votable?-source=II/183Ahttps://vizier.iucaa.in/viz-bin/votable?-source=II/183Ahttp://vizieridia.saao.ac.za/viz-bin/votable?-source=II/183AGETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/183A/table2 (Standard Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/183A/table2?https://vizier.iucaa.in/viz-bin/conesearch/II/183A/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/183A/table2?GETtext/xml+votable180.050000true7.5375-46.522780.0055555555555555565/7845 6/2 530 546 17532 17749 17751 17790 17840 17841 17879 18028 18029 18030 18101 18132 18149 18450 18496 18748 18774 18779 18782 18800 18801 18854 18860 18861 18906 19033 19093 19095 19136 19138 19141 19586 19970 21756 21844 21914 22100 22120 22121 22869 22927 22938 22949 22960 23101 23145 23147 23148 23718 23735 23789 25751 25849 25915 25946 25988 26024 26025 26031 26174 26175 26260 26261 26678 26740 26808 26916 26964 26965 26972 27021 27034 27045 27049 27187 27235 27238 27324 27408 27419 27459 27462 27731 30042 30043 30121 30123 30357 30400 30440 30754 30771 30833 31014 31064 31065 31139 31144 31145 31419 31468 31470 31554 31559 31595 31730 35378 35379 40430 44916 48927 48985 490423.374502503080169e-19 3.921900021377621e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/183A?format=asciiOpticalInfrareddefaultII/183A/table11RCA 3103A photomultiplier No N49701QEQuantum efficiency%instr.det.qefloatrecnoRecord number assigned by the VizieR team.
