Notes:

  • Corrections have been applied to the Voyager 2 H and He flux data from June 27, 2019 (DOY 178/2019) due to the turn off of the Voyager 2 CRS Heaters.
    See Voyager-2 Temperature Corrections for additional information.

  • Corrections have been applied to the Voyager 1 H and He flux data from May 19, 2022 (DOY 139/2022) due to the turn off of the Voyager 1 CRS Heaters.

  • Corrections for the z > 2 portion (i.e. B, C, O, ...) of the spectral analysis for Post-Heater-Turn-Off times are still in validation. Use with caution.

The data units are "Particles / M^2-S-Sr-MeV/nuc".
