Fermi-LAT and H.E.S.S. flux points for the SED obtained around the 2020 periastron (orbital phase 0.97–1.05). The total periastron model as well as the individual components from White et al. (2020), assuming a radial distance of the gamma-ray emission of 20 au as is discussed in the text, is shown. The individual components denote the absorbed hadronic and secondary leptonic components from both winds. The dashed line denotes the unabsorbed model.
