Abstract

The optical luminosity function derived from quasars with M(B) less than -23 is extended to include the nuclear luminosities of Seyfert 1 galaxies. The model is fitted to the (total) luminosity data for active galaxies from a complete flux-limited survey. A good fit is obtained with dN/dL varying inversely as L exp -1.2, matching onto the steeper quasar luminosity function near M(B) = -22. Using a luminosity evolution model derived from quasar data, this feature compares well with the results from faint quasar surveys. 26 references.
