The HFI sampling rate is approximate and subject to on-orbit tuning. Noise figures give values in CMB thermodynamic units. FWHM based on a Gaussian fit to the realistic beam models mentioned in text. References: Ashdown et al. (2009); Holmes et al. (2008); Planck Collaboration (2006).
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.
