Effective temperatures (Teff) and interstellar extinctions (A0) for 46900 Hipparcos stars based on their optical BV and infrared (2MASS) JHK photometry are presented. The stellar parameters were inferred using a Bayesian method. In addition to the Mean parameter estimate (Mean of the posterior probability distribution), the catalogue also provides the Lower and Upper values of the 90% confidence interval (CI) of the probability distribution. Estimates are provided for two methods: the p-model, which uses only the BVJHK colours (and uncertainties thereon); the pq-model, which additionally uses the apparent V-band magnitude and the Hipparcos parallax (plus uncertainties) as well as parameter prior distribution formed from a model Hertzsprung-Russel Diagram. Note that A0 is an extinction parameter and is not quite identical to the extinction in the V band. An explanation of why this is so, plus a convenient conversion equation, are given in the article.
