Scientific paper

Photometric parameters for 2.4 million Tycho stars, including B and V from the Hipparcos mission (Perryman et al., 1997, Cat.I/239/) and J, H, and K from 2MASS (Cutri et al., 2003, Cat. II/246), including standard errors. Proper motions from Hipparcos are also included. Temperatures and distances are estimated from broadband B,V,J,H, and K photometry for dwarfs and giants. For dwarf stars, [Fe/H] metallicity, probability of multiplicity, and more precise effective temperature are estimated from polynomials of broadband colors.
