Abstract

We study the possibility to classify the stars with the use of the photoelectric spectrum scanner designed at Astronomisches Institut at Bochum using a spectral resolution of about 10 Å. We analyse temperature and luminosity effects in two spectral indices which were expected to be promising as spectral classification criteria from previous studies.
