Notes. Given that, for the HFI channels, the sky area corresponding to the PCCS2 and PCCS2E is different for every channel, the comparison between frequency channels must necessarily be performed on the union of the PCCS2 and PCCS2E. The fraction matched from the same analysis applied to the previous PCCS is shown in brackets in the last column, for comparison purposes. Note that 217 GHz is different from other bands in the ratio of the number of above-and-below matches compared to the number of above-or-below. This is of course because of the change of spectral index at that point, as discussed in Sect. 4 and Figs. 25 and 26.
