Abstract

This paper discusses the L-M relation for AGNs, in view of the currently available data and the present understanding of the theory of active galactic nuclei. I review all data sets that are, in my opinion, reliable enough to deduce a cross correlation size for the BLR (only 5 objects) and discuss some important information about the gas distribution that can be extracted from them. An apparent contradiction between different observations of NGC 5548, and the transfer function for the NGC 4151 Hß line, are the best evidences for the existence of a thick geometry in those objects. The complications due to the non-linear response of several emission lines are also discussed, and a preliminary L-M relation is suggested.
