Data Description

Level	Product	Description
1	3D Count Distributions	Counts in 256 energy-deflection steps x 32 azimuth position counters at 12 bits and at 1 second cadence
1	1D Count Distributions	Counts in 256 energy-deflection steps x 2 total event counters at 16 bits and at 1 second cadence
2	3D Phase Space Densities	Validated electron phase space densities (s3 cm-6) in 256 energy-deflection steps x 32 azimuth position counters at 12 bits and at 1 second cadence. Utilizes latest updates to sensor calibration factors.
3	Moments of the Electron Phase Space Distribution	Electron Density, Speed, and Temperature derived from the Level-2 Phase Space Densities and corrected for spacecraft potential
3	Spacecraft Potential	Potential of the EEA instrument relative to the surrounding plasma
3	2D electron energy-pitch-angle distributions	Combined with magnetic field measurement to produce 2D energy-pitch-angle distributions
QL	3D Phase Space Densities (Unvalidated)	As in Level 2, but unvalidated and computed using preliminary sensor calibration factors
QL	Moments of the Electron Phase Space Distribution (Unvalidated)	As in Level 3, but computed from the Quicklook Phase Space Densities and not validated
QL	Spacecraft Potential (Unvalidated)	Unvalidated Potential of the EEA instrument relative to surrounding plasma

Calibrating Data

Data products below level 2 generally require calibration to be transformed into scientificically useable units. This section describes how to calibrate data files from lower to higher levels.
