Primordial Non-Gaussianity in the Cosmic Microwave Background
Figure 6
(a) Constraints on local using WMAP 3-year data as a function of maximum multipole used in the analysis. The red circles are the results obtained using near optimal estimator by Yadav and Wandelt [28]. The green triangles are using the the near-optimal estimator by Smith et al. [122]. The blue square results are obtained using either the optimal estimator by Smith et al. [122]. For all the three analysis Kp0 mask was used. (b) Comparison between the 5-year results (optimal estimator, raw maps) reported in Komatsu et al. [48] and results obtained using the optimal or suboptimal estimator by Smith et al. [122].
