Notes. Summary of the SED parameters for the two Fermi/LAT spectra considered (low-energy threshold equal to 300 MeV and 1 GeV) and for the two cases proposed in the Swift/XRT analysis (case A and case B). For all the cases considered, the minimum and maximum Lorentz factors of the electron distribution are set to γe,min = 300 and γe,max = 5    ×    106 respectively; the angle to the line of sight is θ = 1°, the Doppler factor is δ = 30, and the index of the electron distribution after the break is α2 = 4.0. The electron-distribution normalization parameter K is in units of cm-3; the magnetic field B is in G; the emitting-region size R is in cm; the energy densities ue,B are in erg cm-3; the variability timescale τvar is in hours and the jet luminosity Ljet is in ergs s-1.
