MFs curves for SMICA at N_side = 1024 and ℓ_max = 2000, for the four functionals v_k: a) area, b) perimeter, c) genus, and d) N_cluster. The curves are the difference of each normalized MF, measured from the data, to the average from Gaussian Planck realistic simulations (not lensed). The difference curves are normalized by the maximum of the Gaussian curve. To compare the curves to the presence of primordial NG, the average difference curves for non-Gaussian simulations with is also represented (100 simulations).
