Fig. 9

SEDs for Mrk 421 with two hadronic models where muon-synchrotron emission dominates the TeV spectrum. These solutions correspond to a spectral index n1 = 1.7 and 1.9, a magnetic field with log B [G] = 1.9 and 1.5, respectively, and an emission region of size log R [cm] = 1.5 × 1014 and 5.7 × 1014, respectively. See Fig. 2 for a description of the different curves. The dataset is described in the text.
