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

<table>Fermi-LAT light curves for GRB130427A (bin size of 3 seconds). Photons selected within 10 degrees of the GRB130427A optical position. The contribution from the subset of photons within 3 degrees of the GRB130427A optical position is shown in blue.</table>
