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).",
