Wind Energetic Particle Acceleration, Composition and Transport (EPACT)/LEMT 1-Hr Spin-Sectored H,He,O,Fe Counts for Events
Description
This data set contains hourly counts of H, He, O \nand Fe nuclei in 16 look directions about the spacecraft spin axis. \nCounts for each of the four species are given at 2.5-5 MeV/n, and an \nadditional count is given for 5-8 MeV/n He. As of 10/2011, the data \ncover 39 1997-2006 multi-day intervals that include energetic solar \nparticle events. ASCII data words are comma-separated. For a given \nparticle event, there are species-specific files. File naming uses \nthe convention XX_sec_YYYYMMDD, where XX = H, He2 (2.5-5 MeV/n), \nHe5 (5-8 MeV/n), O or Fe, and where YYYYMMDD is the day of the first \nrecord of the file. Sectoring is defined with respect to the \necliptic plane projection of the concurrently measured magnetic\nfield vector. The edge of sector #1 is coincided with the projection \nof B on the ecliptic plane, so phi value of the center of sector i \nis phiB+11.25+(i-1)*22.5 deg, where phiB is the longitudinal angle \nof B.
