Pioneer 11 Geiger Tube Telescope (GTT) 24-hr count rate data
This data set holds 24-hour-averaged count rates and \nrelated parameters 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. Data have been corrected for RTG and temperature effects.\nSingle-sensor count rates are from the A (directional fluxes of \n0.04-21 MeV electrons and 0.61-80 MeV protons, plus omnidirectional fluxes\nof .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 24-hr 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 a VMS-binary-formatted CD-ROM and were converted to\nASCII by GSFC/SPDF in 2010. The data are ftp-accessible in a single \n9-MB file and are also accessible with graphical display from an\nFTPBrowser interface.
