Comparison of the rescaled spectra of the isotropic wavelet coefficients (top panel) and the local degree of anisotropy (bottom panel) for elliptical Gaussian clumps with σ_a = 4 pixels, σ_c = 32  pixels and Plummer profile clumps with R_a = 4 pixels and σ_c = 32 pixels. To test the fit relations for the peaks in the wavelet spectra and the degree of anisotropy, we also show the results for Plummer profile clumps that are smaller by a factor 1/1.7 and larger by the factor 1/0.8.
