Empirical Calibration of Absolute Magnitudes for G-K Dwarfs and Subdwarfs in the Vilnius Photometric System
Calibrations giving l M_V as functions of [Fe/H] and various intrinsiccolor indices of the Vilnius photometric system are derived for G--Kdwarfs and subdwarfs. The calibrations are based only on the stars withknown trigonometric parallaxes and allow one to estimate the absolutemagnitudes with a standard deviation of +/- 0.6 mag. Comparisons of ourcalibrations with the absolute magnitude estimates in the literatureshow a satisfactory agreement.
