Primordial Non-Gaussianity and Bispectrum Measurements in the Cosmic Microwave Background and Large-Scale Structure

Figure 10

Error bars (obtained from Gaussian simulations) for the pure cubic (triangles) and pseudooptimal (stars) implementations of the bispectrum estimator, to be compared to the solid red line, representing the Fisher matrix (Rao-Cramer) bound, saturated by the full-optimal statistic described in the text. (a) Error bars as a function of the maximum multipole included in the analysis. (b) Error bars as a function of the fraction of the sky considered in the analysis. This analysis included both temperature and polarization data, from the study by Yadav et al. in [82].
