Notes. Total clean times of the individual and co-added spectra. The co-added spectra were used in the analysis. In the case of RGS, two co-added spectra were generated for both instruments, one for each spectral order (first- and second-orders).
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.
