Quantum-Spacetime Scenarios and Soft Spectral Lags of the Remarkable GRB130427A
Figure 6
Here shown are the results of a study of the type already described in Figure 5, but now restricting the analysis to photons with energy between 1 GeV and 5 GeV. Again the dotted line and the dashed line estimate, respectively, the and probability that the given frequency of occurrence of spectral lags is a chance occurrence.
