Scientific paper

Formulas, derived by Arellano Ferro and Mendoza in Paper I (1993), to calculate Mv, log g, and (Fe/H) were applied to a group of 73 A, F, and G stars of high galactic latitude previously classified as supergiant stars. The only star that showed, from data on hand, to be luminous, slightly iron deficient, and out of the galactic plane was BL Telescopii. The remainder of the sample either present controversial results or are definitively giant or dwarf stars misclassified as supergiants. Thus, if luminous, young stars indeed exist out of the galactic plane, they are extremely rare.
