Multiwavelength spectrum of PKS 0447-439 during the period November 2009–January 2010. Filled squares represent the Swift/UVOT, Swift/XRT, Fermi, and H.E.S.S. data from low to high energies respectively. Solid and dashed lines show the SEDs with and without the injection of primary electrons. Our model SEDs are corrected for EBL absorption asumming z = 0.2 and using model C of Finke et al. (2010).
