This data set holds 24-hour-averaged 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. Data have been corrected for RTG and temperature effects. 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 24-hr 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 first "Information URL." The data were provided to NSSDC on a VMS-binary-formatted CD-ROM and were converted to ASCII by GSFC/SPDF in 2010. The data are ftp-accessible in a single 12-MB file and are also accessible with graphical display from an FTPBrowser interface.
