In this short paper, the calibration procedure for the absolute magnitudes derived from the Hβ indices will be discussed. These Hβ indices have been measured for the distant OB-type stars in our studies of galactic structure and are discussed in the paper by Bok which is found elsewhere in this volume (Paper 36).
