Spectral energy distribution of NGC 1068 is analyzed by considering an emitting region with R = 100 R_s. The total photon spectrum originating from this region is shown by the solid black line. The solid red line represents the combined contribution of the corona and disk components (template adopted from Murase et al. 2020). Solid blue and green lines represent the synchrotron and ICS emission produced by the secondary particles, respectively. The neutrino spectrum is depicted by the purple line, and the black dashed line represents the injected luminosity of protons.
