Metallicity calibration and photometric parallax estimation: I. UBV photometry

Abstract

We present metallicity and photometric parallax calibrations for the F and G type dwarfs with photometric, astrometric and spectroscopic data. The sample consists of 168 dwarf stars covering the colour, iron abundance and absolute magnitude intervals 0.30 = 0 and sigma = 0.134 dex, and = 0 and sigma = 0.174 mag, respectively, which indicate accurate metallicity and photometric parallax estimations.
