Dependence of the curvature on the local spectral index α, for s = 2 and various levels of the isotropic random fields (same choice of levels as in Fig. 1). The dashed lines refer to cases with β = 1, while the solid lines to β = 2. In this case, the trends are rather insensitive to the level of the random MF, while they are mostly sensitive to the value of β.
