The data are the same as in Fig. 1. The red solid and blue dashed curves show the model synchrotron and Compton components, respectively. (a) Model 1 for p= 1.35, accounting for the observed MeV tail, which corresponds to the approximately maximum jet emission allowed by the data. (b) Model 2 for p= 2.5, in which case the jet emission is well below the MeV tail, which tail is then most likely emitted by hybrid plasma in the accretion flow. See Section 4.4 for details.
