Abstract
Since their discovery the analysis of quasar magnitudes has generally required some form of evolution. Assuming that quasars do not have evolution this paper shows that they have a well-defined intrinsic magnitude distribution that is independent of cosmological models. However the average apparent magnitudes are essentially constant which means that the only cosmological information they contain is that the absolute flux density has a power law distribution. Thus quasar magnitudes, by themselves, are essentially useless for cosmological investigations.
