Luminosity
Functions
•Exact parameters depend on sample. SDSS and 2dF will provide the best
estimates soon (Jon?). Typically
slopes around a = -1, MB = -20 (note that quasars by definition more luminous than
-23).
The normalization factor is on order
of 0.01 per cubic Mpc. I’m not being too exact because
sample biases and other subtleties exist.
Be more exact for your application.
