Search for Non-Gaussianities in the WMAP Data with the Scaling Index Method
Figure 7
The probability densities of the scaling indices for the WMAP 5-year data (dark lines) and for 50 simulations (fainter lines) by using the scale parameter and the KQ75-mask, computed for the original (red) and the mask-filling method (blue). The upper histogram shows the distribution of the full-sky data set, while the middle and the lower ones show the distribution of the northern and southern hemispheres, respectively.
