cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometrykron-cousins-photometryNew BV(RI)C observations of 77 stars in the Hyades are reported and discussed. The new observations are used to test published magnitudes and color indices for that cluster. For values of (V-R)C and (R-I)C published previously by Taylor & Joner (1985AJ.....90..479T and 2005, Cat. <J/ApJS/159/100>), the tests reveal no detectable scale-factor problems. In addition, the tests show that possible zero-point corrections to the published data can be no larger than a few millimagnitudes. These test results indicate that future studies requiring precision photometry for Hyades stars would be well served by selecting data samples from sources as close as possible to the native Cousins system. Tests of B-V photometry published by Johnson & Knuckles (1955ApJ...122..209J) reveal a zero-point ambiguity of approximately 8mmag in the new data that will require further measurements to resolve.2006AJ....132..111Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/111CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/367/111 : A Hipparcos study of the Hyades cluster (de Bruijne+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/111https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/111http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/111https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/111https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/111http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/111GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/111/table2 (New SAAO BV(RI)_C_ data for the Hyades)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/111/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/111/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/111/table2?GETtext/xml+votable180.050000true49.35994947.65580750.0055555555555555565/84 5884 5886 6/75 309 322 333 340 341 342 348 349 1024 1032 1033 1058 1060 23339 23344 23392 23396 23405 23423 23454 23463 23479 23489 23497 23501 23502 23503 23504 23511 23513 23518 23523 23525 23526 23527 23529 23532 23534 23535 23542 23548 23550 24099 24192 24194 24201 24206 24207 24218https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/111?format=asciiOpticalInfrareddefaultJ/AJ/132/111/table2New SAAO BV(RI)_C_ data for the HyadesrecnoRecord number assigned by the VizieR team.
