2.2.9 spase://NASA/NumericalData/Pioneer10/GTT/PT15M Pioneer 10 Geiger Tube Telescope (GTT) 15-min count rate data 2021-03-11T18:39:11Z This data set holds 15-min count rates and related parameters for each of 8 sensors or multi-sensor coincidence modes, as obtained from the U.Iowa Geiger Tube Telescope (GTT) experiment flown on Pioneer 10. Single-sensor count rates are from the A (directional fluxes of 5-21 MeV electrons and 30-80 MeV protons, plus omnidirectional fluxes of .GT.21 MeV electrons and .GT.80 MeV protons), B (directional fluxes of 0.55-21 MeV electrons and 6.6-80 MeV protons, plus omnidirectional fluxes of .GT.21 MeV electrons and .GT.80 MeV protons), C (omnidirectional fluxes of .GT.21 MeV electrons and .GT.80 MeV protons), D (omnidirectional fluxes of .GT.31 MeV electrons and .GT.80 MeV protons), and G (directional fluxes of 0.06 MeV electrons plus omnidirectional fluxes of .GT.21 Mev electrons and .GT.25 MeV protons) Geiger tubes. Coincidence mode rates are given for Geiger tube combinations (A,B), (A,B,C) and (D,E,F). The G and (A,B,C) rates are each given multiple times in the 12 rates of each 15-min record. Additional parameters associated with each count rate include numbers of counts contributing to each count rate, the statistical uncertainty in each rate, and others used in U. Iowa's processing and carried along for posterity. These are described in the document identified in the "Information URL." The data were provided to NSSDC on VMS-binary-formatted tapes and were converted to ASCII by GSFC/SPDF in 2009. The data are available in 6-month ASCII files whose sizes range from ~20MB early in the mission to .LT.1MB late in the mission. Drs. James A.
