Data Access
This data set has eight 6-hour fluxes (3.45-5.15, 30.55-56.47 and 120.7-227.3 MeV protons, 3.44-4.97, 10.03-21.7, 30.67-56.7 and 112.7-413 MeV/n alpha particles, and 2-6 MeV electrons), 28 count rates, and Poisson uncertainties in the fluxes and rates, as determined from the Cosmic Ray Telescope (CRT) on the Pioneer 11 spacecraft. Data are in annual files with consistent end-of-record marks. Spacecraft position data are not given in the data records but are accessible from Helioweb at http://cohoweb.gsfc.nasa.gov/helios/heli.html

These are the Poisson uncertainties in the eight fluxes named above as scalars. In the data records, each immediately follows the flux it refers to.
These are 28 6-hour-averaged count rates corresponding to various telescope sensors singly and in coincidence, and, for some, for various levels of energy deposition in sensors. The documentation cited above gives conditions for each rate: which sensors, which species (one or more), etc.
