Scientific paper

Separate differential luminosity functions are presented for elliptical, SO, and spiral + irregular galaxies in the Coma cluster. The data span a range of more than five magnitudes. There is evidence that the ellipticals taken separately do not fit the simple Schechter function over the entire magnitude interval. Ellipticals are dominant among the brightest galaxies, yet SO's quickly overcome the deficit in numbers at intermediate brightnesses. A comparison of the Coma spiral + irregular galaxies with a local sample indicates a drastic deficiency of faint spirals in Coma. In a related discussion, the reliability of using the parameter M (asterisk) as a cosmological distance indicator is questioned. Variations of morphological mixture within clusters may introduce, by themselves, a scatter of + or - 0.3 to + or 0.5 mag in this parameter.
