Data Access
Data set records contain fluxes of protons in 5 energy
ranges (4-13, 13-27, 27-37, 37-51, >51 MeV), alpha particles in 6 energy ranges
(2-4, 4-13, 13-27, 27-37, 37-48, >48 MeV/n), and electrons in 2 ranges (0.3-0.8,
0.8-2.0 MeV). The fluxes are averaged over intervals of approximately one hour.
Each "data record" (having ending CR and/or LF) spans 4-5 hours and has 10
time-overlapping segments. Each segment has averaging start and stop times plus
words for 13 fluxes and words for the statistical uncertainties in the 13 fluxes.
However, most words in a given segment have fill values, such that good values
for a given flux (species and energy range) and its uncertainty appear only in
a minority of the segments. No spacecraft position information is included.
Data are from the E6 experiment on Helios 2.
