Some corrections for instrument characteristics and measurement techniques have been applied. Per Data Product Description Document, efficiency corrections have not been applied.Ion Event (PHA) words. Individual ion event data, containing full information on incident angles (elevation and azimuth), E/q, TOF and SSD energy in digital and physical units. The resolution of this data product can be 30s or 300s. In Burst mode the resolution can be 4s but this can only be run on average 1% of the time due to telemetry constraints.Usage notes can be found via the SWA DOI at https://doi.org/10.5270/esa-ahypgn6. <_Description>Source: Master/CDFglobalAttributes/TEXT Please acknowledge Chris J.
