Notes. (1)These are the possible time resolutions. For some periods in the solar wind, the highest time-resolution will not provide data with sufficient statistical accuracy. The best, most scientifically useful averaging intervals will be determined ground analyses of the counting accuracy achievable. (2)Data at this resolution corresponds to SWA-HIS Burst mode, which can only be run on average 1% of the time due to telemetry constraints. (3)Data product not included for most telemetry rates.
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.
