P2M/P1M ratio (black markers) and BridgeE/P1M ratio (red markers) as a function of energy. At optical energies (a few eV), the ratios are obtained using the central pixel of the MAGIC camera (Lucarelli et al. 2008). From 100 eV to 100 MeV, ratios are computed based on the light curves shown in Kuiper et al. (2001). From 100 MeV to 30 GeV, Fermi-LAT data were used.
