Scientific paper

We have determined 90 relations between M_{v}, T_{eff} and line depths
ratios R_{λ1}/R_{λ2} of various ion-atom pairs. These
relations have been used for the estimation of the absolute magnitudes
M_{v} of 56 FGK supergiants with an error 0.05-0.30 mag. The application
range is F0-K0, luminosity classes I and II.
