Multiwavelength and neutrino emission from the G20 blazars previously identified as masquerading BL Lacs. We show the leptonic (purple) and hadronic (light green) components of the jet emission; the corresponding neutrino emission is shown in dark green. The error bands show the 1σ uncertainty range. In red is the host contribution, and in blue the spectrum from the accretion disk, broad lines, and dust torus (cf. Fig. 2). The green region represents the allowed energies and fluxes of the peak of the neutrino spectrum so as to satisfy the IceCube limits at the 68% confidence level (cf. Section 2.7 and Appendix A).
