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.

(a)

The 30 GHz channel is only matched with the 44 GHz channel above.

(b)

The 857 GHz channel is matched above with a catalogue extracted from the IRIS maps using the HFIMHW. Both catalogues are cut with the IRIS mask prior to matching.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
