0.1–200 GeV PL and BPL spectra of the 7 GRBs in the E²dN/dE representation, using time range from the 2 × T₉₀ to one day thereafter. Red and black lines show the PL model fits and BPL model fits, respectively. All ±1σ error contours are propagated from errors on the fit parameters. The vertical dashed lines indicate the energy of the most energetic photon detected. The spectra are extrapolated above the maximum photon energy to 200 GeV and are shown as dotted lines. The blue data points are fits with a power law in individual energy bands. The upper limits are calculated with assuming index = −3 (fixed).
