Evolution of the significance of the BS maximum flux excess at an angular scale of 27° for 3 different values of the energy threshold, E_th = 10, 40 and 80 EeV, as a function of the size of the datasets, in units of the ICRC 2019 Auger statistics. The underlying astrophysical scenario is described in the text. The Sun+Planck GMF model is assumed, either with λ_c = 100 pc (on the left), or λ_c = 200 pc (on the right). The shaded areas show the 1σ interval around the average values of ${\sigma }_{\max }^{\mathrm{BS}}$, obtained from 300 independent datasets. The green dashed line represents the 99% upper limit of the BS maximum significance obtained for isotropic datasets for the same ψ = 27° angular scale.
