Interface to produce plots, listings or output files from Voyager 2
Background-corrected ion differential fluxes are from the Voyager-2 Low Energy Charged Particle (LECP) experiment Each record contains daily averages of fluxes and flux uncertainties of Ions in the energy channels shown below.
Statistical uncertainties are Poisson uncertainties, Flux/SQRT(N).
Flux units are: n/(cm^2 sec ster MeV).
