Pioneer 11 Charged Particle Composition (CPC) 1-Hour Count Rates

ResourceID
spase://NASA/NumericalData/Pioneer11/CPC/PT1H

Description
Hourly count rates from U. Chicago Charged Particle Composition Investigation (CPC) carried on Pioneer 11. There are four rates each, for protons and alpha particles, at 11-20, 20-24, 24-29, 29-67 MeV/n. There are four additional count rates, corresponding to 7-17 MeV electrons, Z>=1 ions with E>67 MeV/n, Z>5 ions with E>67 MeV/n, and 2 x minimizing ionizing particles. The data are ftp-accessible in annual ASCII files and via FTPBrowser. The hourly averages were computed from 15-min data (counts, accumulation times, PHA-based box counts, etc.) that are also available via ftp from nssdcftp.gsfc.nasa.gov.
