Comparison of the wavelet spectra and local degrees of anisotropy measured in the anisotropic wavelet analysis for maps containing randomly placed and oriented ellipses with different sizes, all with an axes ratio of 4:1 (σ = 4 ×16 pixels, σ = 8 × 32 pixels, σ = 16 × 64 pixels). By changing the number of the clumps, we introduce different degrees of anisotropy on the scale of the typical distance of the clumps. The wavelet spectra are normalized for amplitude per scale weighting by dividing them by .
