Notes.

^(a)

Planck Collaboration XXVIII (2014).

^(b)

30−70 GHz: as in PCCS, the extragalactic zone is given by | b | > 30°. 100−857 GHz: outside of Galactic region where the reliability cannot be accurately assessed. Note that for the PCCS2E the only sources that occur in this region lie in the filament mask.

^(c)

Minimum flux density of the catalogue in the extragalactic zone after excluding the faintest 10% of sources.

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.
