padre_meddea

A Python package to process and analyze data from the Measuring Directivity to Determine Electron Anisotropy (MeDDEA) instrument on the NASA solar PolArization and Directivity X-Ray Experiment (PADRE) small satellite mission.

PADRE launched on July 23rd, 2025.

Data will become available soon.

For information about the PADRE mission, see PADRESat.
