The purpose of the mission was to make pioneering measurments of the interplanetary medium from the vicinity of the earth\"s orbit to 0.3 AU. "},{"1":"The objective of experiment (E6) was to study high-energy, charged, cosmic-ray particles of solar, planetary, and galactic origin in interplanetary space. Protons and alpha particles with eneries >1.3 MeV/nucleon, and electrons >0.3 MeV were measured within interplanetary space over the range from 0.3 to 1.0 AU. The instrument, a particle telescope with 55-deg field of view, consisted of five semiconductor detectors, one sapphire Cherenkov counter, and one scintillation counter, all enclosed by an anticoincidence cylinder. The telescope was calibrated prior to launch using radioactive sources, particle acceletors, and ground-level muons. It measured protons and alpha particles in six channels (1.3-3.3, 3.3-13, 13-27, 27-37, 37-45, and >45 MeV/nucleon) and electrons in five energy channels (0.3-0.8, 0.8-2, 2-3, 3-4, and >4 MeV). For more detail see pp.253-257 of Raumfahrtforschung, v.19, n. 5, 1975. "},{"2":"The h-a-cr*.dat and h-b-cr*.dat files contains hourly averaged fluxes of electrons, protons and alpha particles in the MeV ranges. The files were written in ASCII-codes. Each record contains 10 hourly averages. The differential fluxes (particles/sq.m, s, sr, MeV) cover, in several bands, the energy range 0.3-2.0 MeV for electrons, 4.0-51 MeV for protons, and 2.0-48 MeV for alpha particles.  Also provided are the integral fluxes of alphas above 48 MeV, and protons above 51 MeV. For some of the energy channels, the standard deviations of the averages are also provided. Each file is preceded by a header record, providing the start and stop times of the data in the file.
