Fig. 4


Crab spectral energy distribution in the 100 MeV–300 GeV energy range. The points with error bars are the Fermi detections before the flare (dark green), during the flare (red), and after the flare (light green). The black dashed line represents the contribution from the pulsar. The black dot-dot-dashed line represents the IC emission from the nebula. The blue and magenta dot-dashed and solid lines are the synchrotron nebula and the total emission before and during the flare, respectively. Arrows indicate the 95% confidence flux limits.
