Classification of galaxies on CCD frames

Morphological classifications of 231 galaxies in and near the Virgo and Ursa Major clusters are reported which show that luminosity classification techniques (LCTs) can be used to determine the luminosities of spiral galaxies with an accuracy of about 0.7 mag on CCD frames. The observations in the d...
