Discrimination efficiency with respect to ΛCDM of the MG model f5(R) with mν = 0.15 eV as a function of statistic, aperture scale, and source redshift. Plots are analogous to those in Fig. 10. Neutrinos significantly enhance the degeneracy of this model with ΛCDM at the two-point level compared to the mν = 0 eV case. This can be seen in the variance plot (upper left), where the discrimination efficiency is less than 18% at all filter scales and redshifts. The higher-order moments show even less discrimination power. On the contrary, peak counts (lower right), again above a 3σ detection threshold, achieve 100% discrimination efficiency for zs = 2.0 at ϑ2, and above 92% for zs ≥ 1.5 at ϑ3.
