Scientific paper

The role of the volume effect of interstellar absorption in assessing the zero-point of luminosity functions of galaxies is examined. The effect of correcting for interstellar absorption is discussed. It is shown that the difference in the zero-point between the author's luminosity function of galaxies and those by van den Bergh (1961), Shapiro (1971), and Huchra and Sargent (1973) is due to the fact that these workers did not take into account the effect of interstellar absorption in reducing the size of volume surveyed. A luminosity function is proposed which adequately summarizes the present knowledge in this regard.
