Pioneer 10 Cosmic-Ray Telescope: 6-Hour Fluxes and Rates

Eight 6-hour fluxes and 28 count rates for protons, alpha particles, and electrons, measured by the Cosmic Ray Telescope on the Pioneer 10 spacecraft. Data includes Poisson uncertainties and is organized in annual files with consistent end-of-record marks. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Analyze temporal variations in proton fluxes based on the 3.45-5.15 MeV and 30.55-56.47 MeV energy channels
• Study solar modulation of alpha particle populations based on the 3.44-4.97 MeV/n and 112.7-413 MeV/n energy ranges
• Model electron behavior in the outer heliosphere based on the 2-6 MeV electron flux data
• Validate cosmic-ray transport models using the 28 count rates and their Poisson uncertainties

Strengths

• Includes eight distinct particle flux measurements across specific energy ranges
• Provides 28 count rates with associated Poisson uncertainties for statistical analysis
• Data is organized in annual files with consistent formatting

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Spacecraft position data is not included in the records and must be sourced separately
