Combined unabsorbed SED using the gamma-ray fluxes from Fermi-LAT (blue) and AGILE/GRID (red), the XMM-Newton (magenta), RXTE (light blue), and INTEGRAL (cyan) average X-ray spectrum, the XMM-Newton OM UV and U band (black stars) fluxes from dM10, the optical spectrum from Masetti et al. (2006) (green), the 2MASS nIR measures and the ATCA radio measures from Hill et al. (2011) (black stars). Overlaid are the simple power-law forms derived from the X-ray and gamma-ray spectra and from the radio-flux ratios as well as the best-fit composite blackbody model to the UV/optical/nIR fluxes.
