Pioneer 11 Geiger Tube Telescope (GTT) 15-min count rate data
This data set holds 15-min count rates and related\nparameters for each of 8 sensors or multi-sensor coincidence modes,\nas obtained from the U.Iowa Geiger Tube Telescope (GTT) experiment flown \non Pioneer 11. Single-sensor count rates are from the A (directional \nfluxes of 0.04-21 MeV electrons and 0.61-80 MeV protons, plus omnidirectional \nfluxes of .GT.21 MeV electrons and .GT.80 MeV protons), B (directional fluxes \nof 0.56-21 MeV electrons and 9-80 MeV protons, plus omnidirectional\nfluxes of .GT.21 MeV electrons and .GT.80 MeV protons), C (omnidirectional\nfluxes of .GT.21 MeV electrons and .GT.80 MeV protons), D (omnidirectional\nfluxes of .GT.31 MeV electrons and .GT.80 MeV protons), and G (directional \nfluxes of 0.61-3.41 MeV protons) Geiger tubes. Coincidence mode rates \nare given for Geiger tube combinations (A,B), (A,B,C) and (D,E,F). \nThe G and (A,B,C) rates are each given multiple times in the 12 rates \nof each 15-min record. Additional parameters associated with each count\nrate include numbers of counts contributing to each count rate, the \nstatistical uncertainty in each rate, and others used in U. Iowa's\nprocessing and carried along for posterity. These are described in\nthe document identified in the first "Information URL." The data were \nprovided to NSSDC on VMS-binary-formatted tapes and were converted to\nASCII by GSFC/SPDF in 2009. The data are available in 6-month ASCII\nfiles whose sizes range from ~20MB early in the mission to .LT.1MB\nlate in the mission.
