Contour charts for the considered configurations of the bispectrum (where ℓ₁ + ℓ₂ + ℓ₃ = 30) in three different channels: 10 (first column), 15 (second column), and 20 (third column). Each line is related to each case analyzed: GNILC output using m_AIC − 1 (first row) and GNILC output using m_AIC (second row). A very similar pattern arises from the results with m_AIC − 1 and the first row for the measurements with the input foregrounds in Fig. 13. These patterns are similar, albeit with a much smaller amplitude, which indicates a severe reduction of foreground levels, but not a complete removal, which is directly identified in our analysis.
