Wind Energetic Particle Acceleration, Composition and Transport (EPACT)/LEMT 1-Hr Spin-Sectored H,He,O,Fe Counts for Events
Listed in NASA Data Portal
This data set contains hourly counts of H, He, O and Fe nuclei in 16 look directions about the spacecraft spin axis.
Description
Counts for each of the four species are given at 2.5-5 MeV/n, and an additional count is given for 5-8 MeV/n He. As of 10/2011, the data cover 39 1997-2006 multi-day intervals that include energetic solar particle events.
ASCII data words are comma-separated. For a given particle event, there are species-specific files. File naming uses the convention XX_sec_YYYYMMDD, where XX = H, He2 (2.5-5 MeV/n), He5 (5-8 MeV/n), O or Fe, and where YYYYMMDD is the day of the first record of the file.

Sectoring is defined with respect to the ecliptic plane projection of the concurrently measured magnetic field vector. The edge of sector #1 is coincided with the projection of B on the ecliptic plane, so phi value of the center of sector i is phiB+11.25+(i-1)*22.5 deg, where phiB is the longitudinal angle of B.
