Each record in a file\n                contains 1-day (24-hour) averages of fluxes and flux uncertainties of\n                ions (Z>=1) in eight contiguous energy channels, from 0.040-4.00\n                Mev/ion. Each file contains a 2-line header that identifies the\n                spacecraft, data type and time resolution, and labels each column of\n                data. Statistical uncertainties represent one standard deviation.\n                \n                Differential (in energy) flux units are: Ions/(cm^2 sec ster MeV).",
