2 20-05-2008 AGN 8 - Torino Reasons for studying SED’s To understand the physical processes underlying AGN emission To understand the physical processes underlying AGN emission To search for luminosity and redshift dependence of AGN broad band spectra To search for luminosity and redshift dependence of AGN broad band spectra To compute the bolometric luminosity and, if the mass estimate is available, the accretion rates To compute the bolometric luminosity and, if the mass estimate is available, the accretion rates To calculate the bolometric luminosity function and its evolution To calculate the bolometric luminosity function and its evolution
