Evolution of the f_NL parameters (solid blue line with data points) and their uncertainties (dashed lines) for the three primordial bispectrum templates as a function of the maximum multipole number ℓ_max used in the analysis. From left to right the figures show, respectively local, equilateral, and orthogonal, while the different rows from top to bottom show results for T-only, E-only, and full T+E. 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, showing the ± 1σ range around the dashed green lines). The results are for SMICA, and assume all shapes to be independent, and that the ISW-lensing bias has been subtracted. They have been determined with the binned bispectrum estimator.
