Scientific paper

We present determinations of black hole masses, bolometric luminosities, and Eddington ratios for a large sample of AGN. We have determined a number of these parameters for the first time using spectroscopic measurements of AGN that we observed with the Lowell Observatory 1.8-m and CTIO 1.5-m telescopes. We compare the various techniques for determining masses of supermassive black holes (reverberation mapping, broad-line region radius vs. luminosity relation, stellar velocity dispersion) to quantify measurement uncertainties and systemic offsets.
