Testing Gaussianity, Homogeneity, and Isotropy with the Cosmic Microwave Background

Figure 7

Histograms for (𝜒²)^𝑙ℓ(_th) (blue), (𝜒²)^𝑙ℓ(_obs) (purple) and for the difference (𝜒²)^𝑙ℓ(_th)−(𝜒²)^𝑙ℓ(_obs) (solid, red line). We show only a few representative figures. The final probabilities are shown in Table 2 and correspond to the area under the solid curve from −∞ to 0. All pdfs are normalized to 1.
