Fig. 3.
Phase-averaged LAT SEDs of the Crab pulsar and the Crab Nebula. The 4FGL model for the Crab pulsar, reconstructed with fixing λ at 2/3, is overlaid for comparison. All upper limits presented are at a 95% confidence level. We overlay the 60 MeV–100 GeV spectrum predicted by PLSEC and the 10–500 GeV spectrum predicted by PL.
