cds-question@unistra.frphotometryinfrared-photometryvisible-astronomybroad-band-photometryWe have calculated improved photonic passbands for the UBVRI, Hipparcos Hp, and Tycho BT and VT standard systems using the extensive spectrophotometric libraries of NGSL and MILES. Using the Hp passband, we adjusted the absolute flux levels of stars in the spectrophotometric libraries so that their synthetic Hp magnitudes matched the precise Hipparcos Catalogue value. Synthetic photometry based on the renormalized fluxes was compared with the standard UBVRI, BT and VT magnitudes, and revised synthetic zero points were determined. The Hipparcos and Tycho photometry system zero points were also compared with the V-magnitude zero points of the SAAO UBVRI system, the homogenized UBV system, and the Walraven VB system.2012PASP..124..140Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/124/140CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)J/AJ/140/1919 : Zero point spectral energy distribution (Engelke+, 2010)J/PASP/120/1128 : Calibrated griz magnitudes of Tycho star (Ofek, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/124/140https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/124/140http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/124/140https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/124/140https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/124/140http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/124/140GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/PASP/124/140/table1Normalized UBVRI photonic responseslam.U?
