Comparison of the electron spectrum (left) and the associated SED (right) between two cooling descriptions for the peak of the June 2015 flaring state of 3C 279. The electron spectra here are again shown in γ³N_e(γ) representation. The bottom panel of the electron spectrum–SED plot displays the ratio between the electron spectra–SEDs in the case of non-continuous cooling (orange solid curves) and the continuous-loss approximation (green dashed curves) in linear scale.
