Notes. The reference energy E0 used here is 100 GeV. For both blazars, the log-parabola fits values are provided. For PG 1553+113, the values for the power-law model, which was marginally disfavoured, are also given. The last column gives the significance, obtained by comparing the χ2 values for the log-parabola model against those for the power-law model, using only statistical errors in the analysis.
