Time-averaged spectral properties of the Crab Nebula measured from 60 MeV to 10 GeV.

Component PL Γ PLEC Γ PLEC Ec TSPLEC − TSPL(a) Integrated flux (b)
(GeV) (10−9 cm−2 s−1)
IC 1.415 ± 0.023 107 ± 5
Synchrotron 3.278 ± 0.011 3.250 ± 0.026 6.6 ± 5.7 1.7 2534 ± 15



Γ is the photon index. Ec is the energy of the exponential cutoff. TSPLEC − TSPL is the difference in test-statistic (TS) between PLEC and PL.


The integral fluxes are based on PL models.
