nside 16 map of P(x < K) based on pixels from the WMAP 7 year nside 512 W-band map. This time, the K-S test is performed on the 1024 nside 512 pixels inside each nside 16 pixel instead of on disks. The upper panel uses N(0,S + N) as the theoretical distribution (by testing the whitened data against N(0,1)), while the lower panel ignores the correlations, instead using N(μ,σ²), where μ and σ are the measured mean and standard deviation of the samples. The former passes the test outside the galactic plane, while the latter fails everywhere, being biased low outside the galaxy.
