Notes. The statistical significances derived by the default bootstrap method and by the MC isotropic simulations are also listed. The MC p-values account for both the amplitude of the anisotropies, and the agreement in their directions. The Gaussian σ values that correspond to the p-values are also listed, for easier comparison.
