Abstract: High-resolution CCD data and a large group of F-G stars of fundamentally determined distances are used here to investigate the intrinsic nature of the M(v) - W(O I) relation and the effect of other atmospheric parameters on this relation. The M(v) - W(O I) relation is not linear in the absolute magnitude range -10 to +21. Introduction of the (b - y)0 color index to represent stellar temperature leads to a calibration of the M(v) - W(O I) - (b-y)0 relationship in the above M(v) range, which can serve as a valuable tool to determine M(v) for F-G field stars. No systematic effect of the turbulent velocity on the calibration is found.
