Notes. Columns give the peak-to-peak (“p-p”) and rms levels for Stokes I, Q, and U maps. Calculated for a pixel size approximately equal to the average beam FWHM. A null value indicates a residual <10^-2 μK_CMB.

^(a)

The total has been computed on maps resulting from the sum of individual systematic effect maps.

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.
