Description

Count Rates, Averaged Over All Sectors, Voyager1, LECP, Filtered, Channel, Calibrated, CadencePT24H

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