Voyager 2 Plasma Wave Spectrometer Data at Uranus

Edited, uncalibrated wave electric field intensities measured by the Voyager 2 spacecraft in the vicinity of Uranus. The data consists of 4-second intervals with field strengths for sixteen logarithmically spaced frequency channels from 10 Hz to 56.2 kHz. This dataset was produced by NASA's Voyager mission and includes calibration tables to convert raw data numbers to physical units.

Use Cases

• Searching for plasma wave events based on uncalibrated electric field intensities.
• Performing trend analysis on wave activity across sixteen frequency channels.
• Calibrating raw data numbers to antenna voltages using the provided ASCII tables.
• Converting calibrated voltages to wave electric field amplitudes using the effective antenna length.

Strengths

• Provides sixteen frequency channels per scan, spaced logarithmically from 10 Hz to 56.2 kHz.
• Includes separate calibration tables (VG2PWSCL.TAB) to convert raw data numbers to calibrated voltages.
• Data gaps are not zero-filled, preserving the integrity of missing complete spectra.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data are edited but not calibrated; raw values require conversion for precise analysis.
