The Model Magnetic Field is IGRF Version 11. Field-aligned Spacecraft Coordinates use the Spacecraft Velocity Vector, hence DeltaB_FAC_V, in specifying the Coordinate system, which is defined as: 'b' along the Model Magnetic Field, 'p' perpendicular, in the Direction of B-cross-vel_Spacecraft, that is, across Track, and 'v' nominally along the Spacecraft Velocity Vector, along Track, completing the Triad v-p-b.

The Model Magnetic Field is IGRF Version 11. Field-aligned/Spin Plane Coordinates use the Spin Plane, hence DeltaB_FAC_SP, in specifying the Coordinate system, which is defined as: 'b' along the Model Magnetic Field, 's' in the Spin Axis cross Model Magnetic Field Direction, that is, in the Spin Plane and perpendicular to the Model Field, and 'p' perpendicular (B ⨯ (Spin Axis ⨯ B)), nominally along the Spin Axis, completing the Triad s-p-b. The Spin Plane Coordinate 's' is in the same Direction as the despun Electric Field 'E along V' Component. Note that 'E along V' is nominally along the Spacecraft Velocity only in the northern Hemisphere, and is nominally antiparallel to the Spacecraft Velocity Vector in the southern Hemisphere. The 'E along V' Electric Field crossed with the p-component of 'deltaB_FAC_SP' contributes to the Field-aligned Poynting Flux. In this s-p-b Coordinate system, positive Field-aligned Poynting Flux is into the northern Ionosphere, but away from the southern Ionosphere. The other Contribution to the Field-aligned Poynting Flux would be from the p-component of the Electric Field crossed with the s-component of the DeltaB Magnetic Field, but the p-component of the Electric Field is mainly given by the Spin Axis Electric Field Measurement. Because one of the Axial Booms did not deploy on FAST the Spin Axis Electric Field is generally not used. Detrended DeltaB Data have bad Data deleted, DEL_MAG_FLAG equal to 1.
