Derived p-values for the angular clustering of the power distribution as a function of ℓ_max, determined for Commander (red), NILC (orange), SEVEM (green), and SMICA (blue), based on 500 simulations. For SMICA, the p-values based on 2500 simulations are also shown (black). The p-values are based on the fraction of simulations with a higher RS, determined over the ℓ-range up to the given ℓ_max, compared to the data. The results shown here have been marginalized over bin sizes in the range Δℓ = 8 to Δℓ = 32.
