CPME data consist of: spin-integrated, 20.48s resolution count rates of protons in ten energy channels (0.29-0.50 to 90-440 MeV), of alpha particles in six channels (0.59-1.14 to 28-52 MeV/n), of Z>=3 particles in five channels (0.70-1.45 to 6-105 MeV/n), of electrons in 3 channels (0.22-2.5 to 0.80-2.5 MeV), of protons and alpha particles mixed in two channels (>35, >50 MeV/n) and uncertainties in all the preceding 20-s rates; spin-integrated, 10.24s count rates of protons in three energy channels (0.29-0.50 to 0.96-2.00 MeV) and of electrons in the three energy channels given above, plus uncertainties and data quality flags for all these 10.24s rates; 10.24s count rates in 8 spin sectors for 0.29-0.50 MeV protons and for 0.22-2.50 MeV electrons and their uncertainties and dataquality flags; 20.48s count rates in 8 spin sectors for 0.59-1.14 and 1.8-4.2 MeV/n alpha particles and for 0.7-3.3 and 3.1-8.8 MeV/n Z>= 3 particles, and their uncertainties anddata quality flags. EPE data consist of 16-sectored, 20.48s counts (not rates) for Z>=1 particles in 0.05-0.22 and 0.22-0.80 MeV/n channels, for electrons in 0.03-0.10 and 0.10-0.20 MeV channels and for Z>=1, E>0.015 MeV/n particles and electrons mixed. Magnetic field data include GSE and GSM cartesian components and direction angles. Plasma data, mainly from the MIT Faraday Cup, include flow velocity, density and temperature. Better sources exist for those desiring only IMP8 magnetic field and/or plasma data. Data are available as daily gzipped ASCII files; spin- integrated, 20.48s CPME count rates are also available with display and subset capability via FTPBrowser.
