Pioneer 10 Geiger Tube Telescope (GTT) 1-Hour Count Rates

Hourly count rates from U. Iowa Geiger Tube Telescope (GTT) carried on Pioneer 10. There are five rates: electrons > 0.06 MeV plus protons

25 MeV; e > 5 MeV plus p > 30 MeV; e >0.55 MeV plus p > 6.6 MeV; e > 21 MeV plus p > 80 MeV; e > 31 MeV plus p > 80 MeV. The data are ftp-accessible in annual ASCII files and via FTPBrowser. The hourly averages were computed at NSSDC from 15-min data still offline (as of Feb. 2009).
