Pioneer 10 Geiger Tube Telescope: 24-Hour Averaged Particle Count Rates

24-hour-averaged count rates from the University of Iowa Geiger Tube Telescope experiment on the Pioneer 10 spacecraft, corrected for RTG and temperature effects. The data set holds rates for 8 sensors or multi-sensor coincidence modes, measuring directional and omnidirectional fluxes of electrons and protons across multiple energy ranges. Data were provided to NSSDC on a VMS-binary-formatted CD-ROM and converted to ASCII by GSFC/SPDF in 2010.

Use Cases

• Analyze long-term trends in energetic particle fluxes based on 24-hour-averaged count rates.
• Study correlations between different particle energy ranges based on data from multiple Geiger tube sensors.
• Model the radiation environment in the outer solar system based on corrected directional and omnidirectional flux measurements.
• Validate or compare historical particle data from the Pioneer 10 mission.

Strengths

• Data have been corrected for RTG and temperature effects, suggesting quality control.
• Includes statistical uncertainty for each count rate, allowing for error analysis.
• Provides data for 8 distinct sensors or coincidence modes, offering multiple measurement perspectives.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
