2.2.9 spase://NASA/NumericalData/Helios1/E6/ParticleFlux/Kunow/ASCII/PT1H Helios 1 E6 (Kunow) Hourly Particle Fluxes in ASCII Format 2021-03-11T18:39:11Z 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 1.
