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 $0.30<(B-V)_{0}<0.68~\mbox{mag}$ , $-2.0<[\mathrm{Fe}/\mathrm{H}]<0.4~\mbox{dex}$ and $3.4< M_{V}<6.0~\mbox{mag}$ , respectively. The means and standard deviations of the metallicity and absolute magnitude residuals are small, i.e. $\langle\Delta[\mathrm{Fe}/\mathrm{H}]_{res}\rangle=0$ and $\sigma=0.134~\mbox{dex}$ , and $\langle\Delta (M_{V})_{res}\rangle=0$ and $\sigma=0.174~\mbox{mag}$ , respectively, which indicate accurate metallicity and photometric parallax estimations.
