Spectral energy distribution of 2011 January − February data (dark (red) symbols) modeled with the one-zone SSC model of Maraschi & Tavecchio (2003). From high to low energies: the deabsorbed MAGIC spectra (asterisk, see text), the Fermi-LAT data (filled squares), Swift/XRT and Swift/UVOT data (triangles: upper (red) for MJD 55 569, lower (blue) for MJD 55 565) and simultaneous KVA data (filled circle, host galaxy subtracted, see text). The light (cyan) symbols report the January − June data of Fermi-LAT (data points and arrows) and MAGIC (the thick oblique line). The (green) open squares are archival data. The dashed line is the model fit using the extreme Doppler factor δ = 60, while the solid line is the model fit with high γ_min and the long dashed line reports the model parameters that produces with smallest χ² (see text and Table 2).
