Beginning of ReadMe : J/ApJS/168/1 Black hole mass estimates (Kelly+, 2007) ================================================================================ Virial masses of black holes from single epoch spectra of active galactic nuclei. Kelly B.C., Bechtold J. <Astrophys. J. Suppl. Ser., 168, 1-18 (2007)> =2007ApJS..168....1K ================================================================================ ADC_Keywords: Active gal. nuclei ; Line Profiles Keywords: galaxies: active - line: profiles - methods: data analysis - methods: statistical - quasars: emission lines Abstract: We describe the general problem of estimating black hole masses of active galactic nuclei (AGNs) by calculating the conditional probability distribution of M_BH_ given some set of observables. We estimated M_BH_ from both CIV and Hbeta for a sample of 100 sources, including new spectra of 29 quasars. Description: We compiled UV and optical spectra for a sample of 100 sources. Optical spectra for part of the sources were obtained by us, at the Steward Observatory 2.3m Bok Telescope on Kitt Peak using the 600 lines/mm grating of the B&C Spectrograph and at the Magellan Baade Telescope using the Inamori Magellan Areal Camera and Spectrograph (IMACS).
