Description
Count Rates, Averaged Over All Sectors, Voyager2, 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).
