The Scorpio-Centaurus Association: II. Spectral types and luminosities of 220 O, B and a stars
Abstract
Spectral types and luminosities on the revised Yerkes (MK) system are given for 6 stars of type O, 201 of type B, and 13 of type A, in the region of the Association. Microphotometer tracings were used to estimate the line ratios. A mean modulus is determined for the certain members of the Association, and variations of the mean modulus with type and luminosity are discussed briefly.
