Voyager 1 Low-Energy Charged Particle (LECP) Background-Corrected Electron Differential Fluxes, Daily Data in CDF Format

This data set contains data from the LECP instrument on the Voyager 1 spacecraft. Each record in a file contains 1-day (24-hour) scan-averaged fluxes and flux uncertainties of electrons in two contiguous energy channels that cover the energy range 26-70 keV. The period 2002/001 through 2012/240 includes electrons measured upstream of the termination shock and in the heliosheath up though ~2 days after the heliopause crossing. The Voyager 1 LECP instrument steps through eight, 45 deg full-angle sectors, spending 192 sec in each sector, yielding a full scan through 360 deg every 25.6 min. The LECP scan plane is nearly parallel to RT-plane of the heliospheric RTN coordinate system. The electron data are averaged over the seven active sectors S1-S7; S8 is behind the sun-shield and not included in the average. -- Electron channels designated EB01 and EB02 -- Data have been corrected to remove background due to penetrating cosmic ray ions -- Electron fluxes and uncertainties (one st. dev.) in units: (cm^2 s sr MeV)^-1 -- Data are 5-point running averages of daily values -- Values -9.900e+01 used for missing or nonphysical data -- Negative year indicates filled data for the associated doy
