Table 21.
Impact of the thermal Sunyaev-Zeldovich (tSZ) effect on fNL estimators for temperature data. First three columns: results for the fNL parameters of the primordial local, equilateral, and orthogonal shapes, determined by the indicated estimators from the SMICA foreground-cleaned temperature map with additional removal of the tSZ contamination. Last three columns: difference with the result from the normal SMICA map (see Table 5), where the error bar is the standard deviation of the differences in fNL for the Gaussian FFP10 simulations when processed through the two different SMICA foreground-cleaning procedures. Results have been determined using an independent single-shape analysis and are reported with subtraction of the lensing bias; error bars are 68% CL.
