|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 2 spacecraft. Accompanying each
flux and count rate is a statistical uncertainty of the
flux or rate. The data are spin-averaged. The data
are in 1020-character ASCII records and consist of:
A. Proton fluxes based on pulse height and rate data
in 7 energy windows, 3.42-5.40, 6.40-11.95, 11.95-22.15,
24.59-28.74, 32.20-45.93, 45.93-57.56, 143.0-204.5 MeV.
B. Alpha particle fluxes based on pulse heights and count
rates in 6 energy windows, 3.24-4.78, 5.00-11.55,
11.55-21.76, 24.53-31.12, 31.35-45.63, 45.63-57.55 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
F. 26 additional count rates corresponding to individual
telescope sensors or sensor coincidences. 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|
