Scientific paper

Calibration relations obtained for the color index (b-y)0 = F (/m1/, r) and absolute magnitudes M(V) = M(V) (beta) for high-luminosity stars are presented. The regions where the calibrations are valid include stars of spectral types ranging from A4 to F3 and luminosity classes from I to II. The calibration relations are used to estimate the distance moduli of 10 supergiants in the LMC.
