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 11. Data have been corrected for RTG and temperature effects.
Single-sensor count rates are from the A (directional fluxes of
0.04-21 MeV electrons and 0.61-80 MeV protons, plus omnidirectional fluxes
of .GT.21 MeV electrons and .GT.80 MeV protons), B (directional fluxes
of 0.56-21 MeV electrons and 9-80 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 0.61-3.41 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
9-MB file and are also accessible with graphical display from an
FTPBrowser interface.
