Intrinsic broadband SEDs of the four observation epochs listed in Table 1. Archival data are shown in grey (MAGIC Collaboration 2020), while the data contemporary to the four epochs are shown in their respective colours. The fluxes predicted by the two-zone leptonic model are shown dashed, while the predictions of the one-zone lepto-hadronic model are shown as solid lines. In both cases, the models are shown to match the intrinsic flux measured by MAGIC, without taking into account γ–γ absorption by extragalactic background light (relevant for TeV photons) and cosmic microwave background (completely absorbing PeV photons). The spectra of emitted neutrinos predicted by the lepto-hadronic model are shown as dash-dotted lines.
