Polarization Analysis of Time Series Magnetometer Data from Parker Solar Probe, Wind and STEREO-A spacecraft During Periods of Wave Activity

Polarization analysis of high-cadence magnetometer time series data for the Parker Solar Probe, Wind, and STEREO-A spacecraft from October 2018 to July 2025 is conducted. The analysis results for wave periods are posted. This data set is over the frequency range of 0.05 to 10 Hz. The polarization analysis consists of the power spectral density, ellipticity, wave normal angle, degree of polarization. For each spacecraft, there are 2 types of data files 1) frequency-time pixels over the mission, each pixel is tagged with polarization parameters and support parameters, only pixels associated with wave activity are included in this dataset, and 2) a summary of the frequency-time pixel files. The data are binary IDL save files.
