Ulysses COSPIN/HET: Ion and Electron Counting Rates

Spin-averaged coincidence counting rates for ions and electrons from the Ulysses spacecraft's High Energy Telescope. The data is provided as 10-minute averages by NASA. The dataset was last updated on March 13, 2026.

Use Cases

• Analyze solar particle event intensity based on 10-minute averaged ion counting rates.
• Study cosmic ray flux variations based on electron coincidence counting rates.
• Correlate particle fluxes with solar activity cycles using time-series data.
• Model energetic particle transport in the heliosphere using spin-averaged measurements.

Strengths

• Data originates from the NASA Ulysses spacecraft mission.
• Time resolution is specified as 10-minute averages.
• Last update date is March 13, 2026.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in a BIN format, which may require specialized tools for access.
