Radio and Fermi-LAT γ-ray fluxes. (a) Total radio flux density (light green), the core flux density (black), and the jet flux density (light blue). The red symbols denote the flux of component 1a4. Vertical solid brown lines indicate the dates of the neutrino detections. (b) Fermi-LAT γ-ray fluxes (red points). Epochs of neutrino detections are marked by the three vertical black lines. The time of increased neutrino flux is highlighted by the gray-shaded area. The tabulated data are available online in Tables C.1 and C.2.
