Quantum-Spacetime Scenarios and Soft Spectral Lags of the Remarkable GRB130427A

Figure 7

Here shown are the results of a study of the type already described in Figure 5, but now restricting the analysis to the time interval from 190 seconds to 640 seconds after the trigger. Dotted/dashed lines represent again the 10%, 1%, and 0.23% probability that the given frequency of occurrence of spectral lags is a chance occurrence.
