Example of an SED fit (WMAP7 # 190). Solid blue parabola: total SED, which includes synchrotron emission, host galaxy, disk and torus emissions; dashed violet line: synchrotron from the jet; green dashed line: torus; dashed cyan line: host galaxy, taken to be a passive elliptical with M_R = −23.7; dashed red line: accretion disk. Orange points: Planck data; green: WISE data; red: SDSS data; magenta: GALEX data. Black points: data taken from the NASA/IPAC Extragalactic Database (NED). At variance with what was done to compute L_d (see text), the luminosities shown here are computed assuming isotropic emission.
