Notes. We compared the PL and the respective LP best-fit spectral model for the reduced energy range and for the full energy range for each EBL model considered. The energy range is given in TeV and ϕ0 is given in units of 10−13 cm−2 s−1 TeV−1. The decorrelation energy of the PL spectral model was used as the reference energy, given in TeV in the table.
