vs. plane. Sources are divided according to their classification in the 5BZcat: blue circles for 5BZQs (FSRQ), red empty circles for 5BZBs (BL Lacs), and green triangles for 5BZUs (unclassified). Blue and purple dashed lines correspond to calculated from numerical simulations considering SSC and EC scenarios incorporating the transition from TH and KN regimes. The vertical dot-dashed line indicates the ν^Syn domains for which TH and KN regimes apply. The black dashed line represents Eq. (3) using Bδ/(1+z) ≈ 1.3 gauss, with no correction for the TH to KN transition.
