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 by 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)These elements are more difficult to resolve. Appropriate time resolutions will be determined in flight. (4)Additional charge states may be produced during periods of high counting statistics.
