Fig. 6.


Spectral energy distributions (SED) of the Crab Nebula for different flux states. The IC component (the dotted line) is determined with the time-averaged spectrum (in black). The spectra of the high and low states (in red and blue respectively) are defined based on the 60 MeV–600 MeV light curve of the Crab Nebula (Fig. 2). The solid lines and the binned spectra represent the total Syn+IC emission, while the dashed lines represent the synchrotron component. For the low state (solid blue line), the combined Syn+IC spectrum is plotted as a single PL component. The solid cyan line is an alternative low-state spectrum for cross-checking (see the text for detail).
