摘要：
Equivalent widths of 19 absorption lines in CCD slit spectra of 490 stars are compared with their respective (B - V) colors and their absolute magnitudes derived from Hipparcos parallaxes. Algorithms are found which yield the absolute magnitudes for all spectral types with an average error of 0.26 magnitudes. The. (B - V) colors can be reproduced with an average error of 0.020 magnitues.
