V. Malyuto et T. Schmidtkaler, QUANTITATIVE SPECTRAL CLASSIFICATION BASED ON PHOTOELECTRIC SPECTRUM SCANNER MEASUREMENTS OF F-K STARS, Astronomy and astrophysics, 325(2), 1997, pp. 693-699
New criteria of quantitative spectral classification have been introdu
ced and the method of stepwise linear regression to these criteria for
quantitative spectral classification of F-K stars has been applied to
the Bochum photoelectric spectra.
