Description

These Electron Current Spectra in the Jovian Magnetosphere are from the Plasma Spectrometer (PLS) Instrument on Voyager 1 during March 1979 Flyby of Jupiter. The Instrument has four Faraday Cups A, B, C, and D, the Electron Data come only from Faraday Cup D. The Data are specified in Terms of Current per Faraday Cup in femto-amperes (10^-15 A equals 1 fA) versus Channel Number and Energy (eV). This Data Set is for the PLS E2 Mode covering Electron Energies from 10 eV to 5950 eV in 16 logarithmic Energy Channels. The PLS Instrument samples only one Mode of Electron (E1, E2) or Ion (L, M) Spectra in each Time Interval, so the E2 Data are not continuous but consecutive with the other Modes in Time.

Caveats
In E2 Mode, there are 16 logarithmic Energy Channels covering 10 eV to 5950 eV. The 17 bounding Energies of the 16 Channels are computed from Ei = [60(1.33352)^(i-1) - 50] eV for i from 1 to 17.
