Parameter estimation histograms for 100 maps with linear model non-Gaussianity with k_c = 0.01 and l_max = 1000. The maps were created with f_NL = 500 and φ = 0° (first two rows) and φ = 45° (rows three and four). Top: reconstructed f₁ (green) and f₂ (blue) amplitudes for φ = 0°. Second row: corresponding reconstructed amplitudes f_NL and phases φ. Third and fourth row: same as above but with phase φ = 45°.
