cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometrymedium-band-photometryAmong several EB distance algorithms, direct comparison of observed and theoretical fluxes is particularly straightforward, although it requires absolute flux calibrations for which only a modest number of publications exist. Here, we measure UBV RI and uvby flux calibrations and calibration ratios from astronomical objects in ways not previously tried, specifically for EBs, single stars within 80pc, and the Sun. All of the single stars are below about 6500K temperature. Interstellar extinction is avoided by a restriction to nearby targets. Some photometric band calibrations in the literature are accurate enough for very good EB distance determinations if star temperatures are accurately known, especially considering that estimated distance has only a square-root dependence on calibration constant, but accurate band-to-band calibration ratios are keys to the combined temperature-distance problem. Band-independent canceling factors (star radii and distances) allow calibration ratio measurement with enhanced accuracy, compared to individual band calibrations. A physical EB model with embedded stellar atmosphere emission optimally matches theory to observations for the binaries. Single star candidates are identified as reliably single if their radial velocity variations are below 100m/s. For the most part, we find good agreement with some of the previous calibrations and the ratios are improved.2010ApJ...723.1469Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/723/1469CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/130 : Geneva-Copenhagen Survey of Solar neighbourhood III (Holmberg+, 2009)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)V/121 : Catalog of DMS-type eclipsing binaries (Svechnikov+, 1999)II/215 : uvby-beta Catalogue (Hauck+ 1997)II/183 : UBVRI Photometric Standards (Landolt 1992)II/116 : Photoelectric Photometry in Johnson UBVRI System (Lanz 1986)J/A+A/498/527 : Calibration of Stromgren phot. for late-type stars (Onehag+,J/AJ/137/4186 : UBVRI standards around celestial equator (Landolt, 2009)J/A+A/487/1081 : uvby photometry of 6 eclipsing binaries (Clausen+, 2008)J/A+A/487/1095 : Radial velocities of AD Boo, VZ Hya, WZ Oph (Clausen+, 2008)J/PASP/120/1128 : Calibrated griz magnitudes of Tycho star (Ofek, 2008)J/MNRAS/389/585 : Fundamental parameters of M dwarfs (Casagrande+, 2008)J/AJ/133/2502 : UBVRI Standard Stars (Landolt, 2007)J/MNRAS/373/13 : Lower MS stars fundamental param.
