The data set contains despun data including the following parameters: scalar magnetic field strength; vector magnetic field in Cartesian GSM and SM coordinates; spacecraft radial distance from the center of Earth; spacecraft position in Cartesian GSM and SM coordinates; despin method indicator (0: not despun; 1: optical aspect; 2: sun pulse; 3: array voltage; 4: mag field model; 4/5: solar array method); and an estimate of the angular uncertainty in magnetic field direction (set to zero for despin = 1 or 2).
