Notes. Column 1 shows the period of observations, Cols. 2–4 the fitting model and its parameters (PL: power-law model, Log P: log-parabola model. See definitions in the text), Col. 5 the TS, Col. 6 the difference of the logarithm of the likelihood of the fit with respect to a single power-law fit. The flux >100 MeV is given in the last column.
