Notes. The value Ecut, 95%
is the statistical 95% confidence lower limit on the energy cutoff of the FBs spectrum;
is the minimal95% statistical lower limit among the models of the FBs in Sects. 3.2–3.4. There are four cases in which the introduction of a cutoff does not lead to improved fit: in all of these cases
while the formal best-fit values of Ecut are larger than 1 TeV.
