Voyager 2 CRS: Electron Counting Rates at Neptune, 6-Second Resolution

Voyager 2 Neptune Cosmic Ray Subsystem (CRS) Electron Telescope D1 Counting Rates, Version 1.0, provides high-resolution data from the Voyager 2 spacecraft's encounter with Neptune. The dataset contains 6-second average counting rates from the D1 detector, which nominally responds to electrons with kinetic energies above approximately 1 MeV. This data was produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling the omnidirectional flux of >1 MeV electrons based on the D1 counting rate parameter.
• Analyzing temporal variations in cosmic ray background near Neptune based on the 6-second sampling interval.
• Applying deadtime corrections for high-count-rate events based on the described ~20 µs discriminator deadtime.
• Calibrating detector response using the provided D1 response function R(E,θ) tables.

Strengths

• Data has a high temporal resolution of 6.0 seconds.
• Background noise level is specified as 0.000 counts/second.
• Detailed calibration and correction methodology is provided, including a saturation level of approximately 50,000 counts per second.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data points are 6-second averages taken once every 96 seconds, which may not capture all transient events.
