ZCB 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). Please acknowledge the LECP PI (S.M. Krimigis) and the lead LECP CoI (R.B.
