Taking advantage of the significantly larger color range covered by these observations, we derive in the present paper high precision calibrations of the surface brightness-color relations using exclusively Cepheid observations. These empirical laws allow to determine the distance to Cepheids through a Baade-Wesselink type technique. The least dispersed relations are based on visible-infrared colors, for instance FV(V-K)=-0.1336+/-0.0008(V-K)+3.9530+/-0.0006. The convergence of the Cepheid (this work) and dwarf stars (Kervella et al. 2004) visible-infrared surface brightness-color relations is strikingly good. The astrophysical dispersion of these relations appears to be very small, and below the present detection sensitivity.2004A&A...428..587Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/428/587CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/428/587https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/428/587http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/428/587https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/428/587https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/428/587http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/428/587GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/428/587/stars (Star positions and magnitudes (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/428/587/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/428/587/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/428/587/stars?GETtext/xml+votable180.050000true37.95458389.2641670.0055555555555555566/4095 15633 23922 28779 28831 29665 30128 33804 37303https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/428/587?format=asciiOpticalInfrareddefaultJ/A+A/428/587/starsStar positions and magnitudes (from Simbad)NameCepheid namecharprimaryrecnoRecord number assigned by the VizieR team.
