Notes. (a) Radiometers are identified bytheir frequency channel, either 30, 44 or 70 GHz; the feedhorn number, between 18–28; and the polarization arm, either S or M.
(b) Central frequency.
(c) The radiometric quantities 
,
faper, and
fη refer to a u2 SED.
(d) Band average of the synchrotron spectral dependence ν−0.4
(see Eq. (30)) for the 30 GHz and 40 GHz channels.
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.
