Results of the likelihood analysis obtained for our special hypothesis on the source distribution of Sect. 7 (see text). The top panel is built as Fig. 8 and shows the cases of the JF12+Planck GMF (λ_c = 200 pc), the Sun+Planck GMF (λ_c = 50 pc) and a special case assuming the exclusion of galaxies members of nearby rich galaxy clusters from the source distribution and using JF12+Planck GMF (λ_c = 50 pc). On the bottom panel, similarly to Fig. 9, the f_aniso and θ parameters maximizing the likelihood analysis (for the SBG catalogue), for the last two cases shown on the top panel, are plotted against each other.
