======================================================================== Voyager 1: Z>=1 Background-corrected electron differential fluxes ======================================================================== This directory 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 -- Fluxes and uncertainties (one st. dev.) in units: electrons/cm^2-s-sr-MeV -- 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" A record contents is as follows: ----------------------------------------------------------------------- column label description ----------------------------------------------------------------------- 1 year 4-digit year 2 doy day of year (1-365 or 366) 3 dec_year decimal year = year + (doy - 1)/dpy (dpy=365 or 366) 4 EB01_fav flux, electrons 26-37 keV 5 EB01_favu stat. unc. of above flux 6 EB02_fav flux, electrons 37-70 keV 7 EB02_favu stat. unc. of above flux 2023 April 23 Contact: Rob Decker , Voyager 1 & 2 LECP Investigations Co-Investigator Johns Hopkins Applied Physics Laboratory Space Exploration Sector / Space Physics Group
