Pioneer 10 Charged Particle Composition (CPC) 1-Hour Count Rates

ResourceID
spase://NASA/NumericalData/Pioneer10/CPC/PT1H

Description

Hourly count rates from U. Chicago Charged Particle Composition
Investigation (CPC) carried on Pioneer 10. 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.
