Data Access
This data set contains hourly counts of H, He, O
and Fe nuclei in 16 look directions about the spacecraft spin axis.
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.
