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 anti-parallel 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 = 1.'.
