GO A PWS RESAMP SUMMARY IDA SPECTRUM ANALYZER 60S V1.0: Galileo Flyby Plasma Wave Spectra

During the Galileo spacecraft's flyby of asteroid Ida, the Plasma Wave Receiver collected electric and magnetic wave spectra. The data set includes 1-minute averages of spectral densities, binned into 49 electric channels from 6 Hz to 5.6 MHz and 34 magnetic channels from 6 Hz to 75 kHz. This browse data set was produced by NASA from the High Frequency Receiver, Sweep Frequency Receiver, and Spectrum Analyzer.

Use Cases

• Analyze electric field spectral density based on V^2/m^2/Hz measurements
• Study magnetic field spectral density based on nT^2/Hz measurements
• Compare wave spectra across 49 logarithmically-spaced electric channels
• Compare wave spectra across 34 magnetic channels
• Use as browse data for the Galileo flyby of Ida

Strengths

• Data covers electric spectra from 6 Hz to 5.6 MHz and magnetic spectra from 6 Hz to 75 kHz
• Includes 1-minute averages of spectral densities
• Produced by NASA's Galileo mission instruments

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The spectral resolution is reduced for browse purposes and does not correspond to the instrument's 158 specific channels
