Top left panel: Gaussian reconstructed map filtered for scales k ≳ 0.3 arcmin⁻¹. Top right panel: fractional Brownian motion simulation with the same power law as the Gaussian part of Polaris. The fBm is also filtered for k ≳ 0.3 arcmin⁻¹. Bottom left panel: intermittency measure as defined in Eq. (23) for the Gaussian segmentation of wavelet coefficients. Bottom right panel: intermittency measure of the fBm simulation on the same spatial scales as Polaris.
