Interface to produce plots, listings or output files from Voyager 1
Ion data are from LECP instrument on the Voyager 1 spacecraft. Each record in a file contains 1-hour averages of fluxes and flux uncertainties of ions (Z>=1) in eight contiguous energy channels given below
Statistical uncertainties are Poisson uncertainties, Flux/SQRT(N).
Flux units are: Ions/(cm^2 sec ster MeV/n).
