A Modern Quasar SED from XMM-Newton comma Spitzer comma and SDSS

We request 7 XMMNewton pointings in the field of the Spitzer First Look Surveyto obtain uniform Xray data on 100 quasars, including 10 luminous, type Iquasars from the Sloan Digital Sky Survey. With 14.0 ks exposures (98.0 kstotal), we will obtain more than 500 counts on each of the 10 luminous quasarsand at least 40 counts on 100 other quasars in the field of view. We willcharacterize the Xray, UV, optical, IR, and radio SED of quasars as a functionof various properties, thus permitting better estimates of bolometricluminosity, black hole mass, and accretion rate in addition to providing betterobservational templates for comparison with accretion disk models. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
