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