Notes. For this comparison, we smooth Planck TYPE 1 maps with 10′ apodized beam at Nside = 1024 and compute the noise uncertainty. Similarly, for comparison with Planck TYPE 2 maps we downgrade the TYPE 2 null maps to Nside = 1024 and smooth the xGNILC null maps with a 15′ beam. While these numbers are computed directly from the null maps, they are consistent with uncertainty computed from the simulated xGNILC noise maps.
