Evolution of the f_NL parameters (solid blue line with data points) and their uncertainties (dotted blue lines) for the three primordial bispectrum templates as a function of the minimum multipole number ℓ_min used in the analysis. From left to right the panels show local, equilateral, and orthogonal shape results, while the different rows from top to bottom show results for T only, E only, and full T+E data. To indicate more clearly the evolution of the uncertainties, they are also plotted around the final value of f_NL (solid green lines without data points, around the horizontal dashed green line). The results here have been determined with the Binned bispectrum estimator for the SMICA map, assume all shapes to be independent, and the lensing bias has been subtracted.
