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

Figure 16

We here show in a logarithmic plot a straight line with the slope we determined in Section 3. Also shown (as thick points) are the 7 data points for GRB130427A already shown in Figure 4. The red triangles describe data on four events found on a single spectral-lag straight line in Figure 10 for GRB080916C. The orange point with sizable error bars are for the 3.3 TeV neutrino and the 109 TeV neutrino discussed from our perspective in [32], with 30 percent uncertainty on neutrino energies reflected in horizontal segments and vertical segments reflecting the uncertainty in redshift of the GRB possibly associated to the two neutrinos.
