Quantum-Spacetime Scenarios and Soft Spectral Lags of the Remarkable GRB130427A
Figure 10
Here shown is the Fermi-LAT sequence of photons with energy greater than 1 GeV for GRB080916C. We visualize error bars at the level for the energies of the most energetic events, which play a special role from our perspective. The slope of the straight line here shown is not fit on this data but rather is obtained from the slope fit in Figure 4 (for GRB130427A) by rigidly rescaling it by the factor of dictated by (1).
