This near encounter step data set consists of the counting rate and flux data for electrons and ions from the Low Energy Charged Particle (LECP) experiment on Voyager 1 while the spacecraft was within the very close vicinity of Jupiter. This instrument measures the intensities of in-situ charged particles ( >15 keV electrons and >30 keV ions) with various levels of discrimination based on energy range and mass species. A subset of almost 100 LECP channels are included in this data set. The LECP data are globally calibrated to the extent possible. Particles include low energy electrons, protons, alpha particles, medium energy protons and ions, high energy and intensity protons, electrons, alpha particles, and Z >= nuclei. The near encounter data are 48.0 second rate and flux measurements within 1/8 of the LECP instrumental motor rotation period (the angular scanning periods, or step period).
