Resource ID:spase://VEPO/NumericalData/Pioneer10/CPC/PT15M | ||||||||||||||||||

| ||||||||||||||||||

This data set contains coincidence mode counts and accumulation times, plus "box counts" based on pulse height analysis (PHA), at 15-min resolution. There are 11 coincidence mode counts and 27 "box counts." Taken together, the parameters included allow computation of average counting rates and of fluxes of protons, electrons, helium and CNO nuclei in selected energy windows corresponding to the PHA boxes. There are 12 proton boxes spanning 3-67 MeV, 5 helium boxes spanning 3-67 MeV/n, 5 electron boxes, 2 Z>2 boxes, 1 box each for CNO, Z>5, and E>67 MeV/n. |

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. |

This data set has eight 6-hour fluxes (3.45-5.15, 30.55-56.47 and 120.7-227.3 MeV protons, 3.44-4.97, 10.03-21.7, 30.67-56.7 and 112.7-413 MeV/n alpha particles, and 2-6 MeV electrons), 28 count rates, and Poisson uncertainties in the fluxes and rates, as determined from the Cosmic Ray Telescope (CRT) on the Pioneer 10 spacecraft. Data are in annual files with consistent end-of-record marks. Spacecraft position data are not given in the data records but are accessible from Helioweb at http://omniweb.gsfc.nasa.gov/coho/helios/heli.html |

---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

Resource ID:spase://VEPO/NumericalData/Pioneer10/GTT/P1D | ||||||||||||||||||

| ||||||||||||||||||

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 10. Data have been corrected for RTG and temperature effects. Single-sensor count rates are from the A (directional fluxes of 5-21 MeV electrons and 30-80 MeV protons, plus omnidirectional fluxes of .GT.21 MeV electrons and .GT.80 MeV protons), B (directional fluxes of 0.55-21 MeV electrons and 6.6-80 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 0.06 MeV electrons plus omnidirectional fluxes of .GT.21 Mev electrons and .GT.25 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 12-MB file and are also accessible with graphical display from an FTPBrowser interface. |

C3 corresponds to >650 MeV/n ions (typically 30% protons and 70% Z>1 nuclei). M1L corresponds to >80 MeV/n ions (typically 90% protons and 10% Z>1 nuclei). M3L corresponds to 80-300 MeV protons (50%) and >80 MeV/n Z>1 nuclei (50%). The data are ftp-accessible in annual ASCII files and via FTPBrowser.

Resource ID:spase://VEPO/NumericalData/Pioneer10/TRD/PT30M | ||||||||||||||||||

| ||||||||||||||||||

This ASCII data set contains 30-min count rates for 21 "pulse-counting" channels from a Cerenkov counter (which measures, via 3 discrimination levels, electrons >6 MeV plus nuclei >480 MeV/n, electrons >9 MeV plus nuclei >550 MeV/n, and electrons >13 MeV plus nuclei >650 MeV/n), an electron scatter detector (nuclei >80 MeV/n and electrons >0.16, >0.255, >0.46 MeV), and a minimizing ionizing particle counter (nuclei >80 MeV and electrons >35 MeV. The data set also contains 30-min averaged currents from the Cerenkov counter and two scintillators, spacecraft position and attitude data, and various other statistical and housekeeping data. The electrometer-based currents data are not reliable. The data are all for mission cruise phases and not planetary encounters. |
