Distribution of the IceCat1+ neutrino events in terms of the error region size (Ω) and signalness (𝒮) shown for: (A) the published and (B) the enlarged error region scenarios (see Sect. 3.3). The neutrino events that have at least one blazar association are shown as cyan stars while those that have no blazar association are shown as blue dots. The horizontal dotted line shows $\stackrel{\sim }{\mathrm{\Omega }}$ (median Ω of IceCat1+). The weight as calculated by Equation 3 is shown as a heat-map ranging from 0 to 1. Note that in these plots 13 neutrinos with Ω > 100 deg² are not shown.
