Search for Non-Gaussianities in the WMAP Data with the Scaling Index Method

Figure 3

The two plots on the left-hand side illustrate the original 5-year WMAP data of the coadded VW-band (above) and the related colour-coded 𝛼-response (below) for a scaling range of 𝑟=0.175. The galactic plane and several secondary spots are masked out by the KQ75-mask [46]. The equivalent plots for the mask-filling technique are arranged on the right-hand side.
