1. Introduction

In Paper I (Schmidt-Kaler and Malyuto, 1996) we began to study the classification of stars by means of photoelectric scanner spectra obtained at Astronomisches Institut at Bochum (resolution 10Å). Two criteria (the ratios of intensities in selected intervals including the hydrogen line , G-band and some ajacent strong metallic lines) were shown to be indicators of spectral and luminosity classes. In the present paper we extend the measurements to other spectral intervals, produce additional criteria and outline a scheme of quantitative spectral classification of F-K stars which may be applicable to galactic studies.
