Description

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 < (B -V)(0) < 0.68 mag, -2.0 < [Fe/H] < 0.4 dex and 3.4 < M-V < 6.0 mag, respectively. The means and standard deviations of the metallicity and absolute magnitude residuals are small, i.e. = 0 and sigma = 0.134 dex, and = 0 and sigma = 0.174 mag, respectively, which indicate accurate metallicity and photometric parallax estimations.
