Fig. 2.


Neutrino flux of a source detected with one (main panel), two, or three (smaller panels) neutrino events. The red bands show the real neutrino flux of the sources that produce the signal with 90% and 99% probability. For a single detected event, the source flux can be biased to lower values by several orders of magnitude compared to the flux inferred from the detected event (90% and 99% Poisson errors shown in blue). For this figure we assumed that the population in total produces 10 neutrino events (within a given time). While the selection bias is strong for sources detected with a single event, it quickly vanishes as soon as three or more events are detected from the same source. The effective densities of several source classes are indicated (compare Table 1).
