Interface to produce plots, listings or output files from Voyager 2
Data are from the Voyager-2 Low Energy Charged Particle (LECP) experiment. Each record contains 1-hour averages of fluxes and flux uncertainties of protons and Ions in the energy channels shown below.
Statistical uncertainties are Poisson uncertainties, Flux/SQRT(N).
Flux units are: Protons/(cm^2 sec ster MeV).

The annual files of this ASCII data set may be accessed from FTP SPDF or JHU/APL
