Intrinsic time delays at gamma-ray energies obtained for a pure SSC scenario, for the set of parameters given in Table 1 (black curve, 87 mG) and for two other values of the magnetic field, 50 mG (blue) and 130 mG (red). The different trends (increasing in blue, flat in black, and decreasing in red) are here obtained only from the variation of the magnetic field amplitude ||B||, and start to appear at E ∼ 100 MeV.
