VOYAGER 2 LECP: Calibrated 15-Minute Charged Particle Data from Jupiter Flyby

Almost 100 channels of resampled, calibrated data from the Low Energy Charged Particle (LECP) experiment on Voyager 2 during its Jupiter encounter. The data, provided by NASA, consists of time-averaged 'rate' measurements for electrons >26 keV and ions >30 keV, with full angular anisotropy information preserved over 15-minute intervals. The dataset requires conversion to physical units based on contextual analysis of particle mass species and background contamination.

Use Cases

• Analyzing charged particle intensity and anisotropy near Jupiter based on the 15-minute averaged rate data.
• Studying energy spectra and mass species discrimination for particles >26 keV (electrons) and >30 keV (ions).
• Modeling background contamination and calibrating instrument data using the shielded sector 8 rates mentioned in the description.
• Investigating temporal variations in the Jovian magnetosphere based on the preserved angular scanning information.

Strengths

• Data is globally calibrated to the extent possible, as stated in the description.
• Full angular anisotropy information is preserved due to a rotation cycle faster than the 15-minute averaging period.
• Includes a subset of almost 100 LECP channels with associated geometric factors and energy bandpass parameters.

Limitations

• Data is in 'rate' format, not converted to standard physical units, requiring manual conversion based on uncertain mass species and background determinations.
• Some channels are subject to serious contaminations, as noted in the incomplete description.
• Column-level documentation is absent; field semantics and data structure must be inferred after download.
