Probability of observing one multiplet as a function of the number of correlations. We consider the 43 BL Lacs contained in the 2FHL Fermi-LAT catalog in the region 0° ≤ δ ≤ 30°. The luminosities of BL Lacs are taken into account in the calculation of the expectations. The expected number of correlations, assuming that the BL Lacs are the main emitters of high-energy neutrinos (Eq. (23)), is indicated by the vertical band.
