Notes. Suffixes a and b denote the different LO-chains available for this receiver channel to extend their RF-coverage. It is not possible to swap these LO-chains during flight. Status: channels L1 and L2 were operated during Early and Basic Science, Ma during Basic Science only; Mb and H are under development (see the following sections).
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.
