Map of the local degree of anisotropy |m^a(s, x)|∕mⁱ(s, x) for the Polaris column-density map when using the -filter with a size ofs = 0.56 pc = 0.21°. The white contour at a value of 0.5 separates regions dominated by anisotropic fluctuations from those dominated by isotropic fluctuations. There is no obvious correlation to the corresponding map of wavelet coefficients shown in the lower panel of Fig. 29.
