Helios 1 E7 (Trainor) 30-min fluxes and rates
Listed in NASA Data Portal
This data set, created in 2010 by Nand Lal, contains 30-min resolution fluxes and count rates of energetic protons, alpha particles, electrons and X-rays from the E7 experiment (P.I.: J. Trainor, GSFC) flown on the Helios 1 spacecraft.
Description
Accompanying each flux and count rate is a statistical uncertainty of the flux or rate. The data are spin-averaged.
The data are in 920-character ASCII records and consist of: A. Proton fluxes based on pulse height and rate data in 7 energy windows, 3.40-6.05, 6.05-11.10, 11.10-21.60, 24.52-28.82, 32.00-46.30, 45.30-57.22, 135.2-206.5 MeV. B. Alpha particle fluxes based on pulse heights and count rates in 6 energy windows, 3.20-4.98, 4.98-11.50, 11.50-21.60, 24.51-31.12, 31.12-45.53, 45.53-57.53 MeV/n. C. Combined proton plus alpha particle fluxes based on LET1 and HET count rates in 6 energy windows, 3-6, 6-11, 11-21, 20-30, 32-45, 45-56 MeV/n.

D. Alpha particle fluxes based on HET count rates in three energy windows, 20-30, 32-45, 45-57 MeV/n. E. Two count rates primarily due to electrons at 2-4 and 4-8 MeV. F. 21 additional count rates corresponding to individual telescope sensors or sensor combinations.
For one sensor, rates at each of several discrimination levels are given). These rates are further discussed in the documentation and in the references provided. A subset of the above parameters (A, B, E) are available with graphical display at the OMNIWeb-Plus interface identified below
