Notes. The pivot energy was fixed to E0 = 1 keV. Only the observations in which the log-parabola model was preferred over the power-law at a significance greater than 3σ are included in this table. For these observations, the best-fit values of the spectral index α, curvature parameter β and normalisation N0 are reported.
