Evolution of the f_NL parameters (solid blue line with data points) and their uncertainties (dashed lines) for the five bispectrum templates as a function of the maximum multipole number ℓ_max used in the analysis. From left to right and top to bottom the figures show respectively local, equilateral, orthogonal, diffuse point sources (all four with the ISW-lensing bias subtracted), ISW-lensing and local again (the last two without subtracting the ISW-lensing bias). To show better the evolution of the uncertainties, they are also plotted around the final value of f_NL (solid green lines without data points). The results are for SMICA, assume all shapes to be independent, and have been determined with the binned bispectrum estimator.
