Notes. The luminosity distance DL or the redshift z of each source is also specified. The flux Φγ,min is the minimum flux required to reach the IceCube sensitivity limit, at threshold energy ϵth or at break ϵb, to be compared with the observed flux of the source Φγ,obs at that energy. Fluxes calculated at ϵb are indicated in brackets. Here ηB = ηp = 1, but the most conservative estimate should use ηp = 100. Starred sources should be viewed with care because of possible hidden radiation (Sect. 6.2).
