Notes. 

(a)

The precise beam values are presented in Zacchei et al. (2011) and Planck HFI Core Team (2011b). This table shows the values which were adopted for the ERCSC.

(b)

Flux density of the median >10σ source at |b| > 30° in the ERCSC where σ is the photometric uncertainty of the source.

(c)

Flux density of the faintest >10σ source at |b| > 30° in the ERCSC.

(d)

Faintest source at |b| > 30° in the ERCSC.

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.
