AP filter outputs for the Gaussian realizations of the V band of WMAP. Results for realizations of other bands are virtually identical to these. The black, green and blue symbols and curves refer to density threshold choices of ν = 2.5, 2.8 and 3.2, respectively. Circles correspond to voids and squares to superclusters, while solid lines display the |$\mathcal {S}/\mathcal {N}$| at each scale.
