> 10 GeV SEDs of the Crab pulsar at different pulse phases observed with LAT and ground-based instruments. The vertical axis shows the differential flux per unit phase (δ). The horizontal axis shows the measured photon energy (unscaled). Be noted that the orange/blue LAT bins presented here are different from those presented in Fig. 4 because the phase ranges are adjusted for comparison purpose. For each phase we investigate, we overlay the spectrum predicted by the joint-instrument fit of PLSF. The PLSEC fit to the broadband LAT spectrum in the full phase (Fig. 3) and its extrapolation are also overlaid for comparison.
