Notes. The average sensitivity per $30^\prime$ pixel or per FWHM² resolution element ( $\delta T$ and $\delta T/T$ , respectively) is given in CMB temperature units (i.e. equivalent thermodynamic temperature) for 14 months of integration. The white noise (per frequency channel and 1 s of integration) is given in antenna temperature units. See Tables 2 and 6 for LFI measured performance.

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.
