Notes. The first column gives results for the fNL parameters of the primordial local, equilateral, and orthogonal shapes, determined using the Binned estimator on the SMICA foreground-cleaned maps. The standard temperature mask is used, but the polarization mask has been enlarged by surrounding every hole by a region either 20 or 40 pixels in width (“Extra 20” or “Extra 40”). The second column gives the difference with the result using the 2018 common mask (see Table 5), where the error is the standard deviation of the differences in fNL for 150 simulations when analysed with the two masks. Results have been determined using an independent single-shape analysis and are reported with subtraction of the lensing bias.
