            <Description>               
                Electric Field in GSE is obtained from CSA C[1-4]_CP_EFW_L3_E3D_GSE. 

                Note that Pi has not validated this product.

                This dataset contains the electric field in the inertial frame (i.e., VxB removed) in the GSE coordinate system, 
                using EFW electric field data from file C[1-4]_CP_EFW_L3_E and interpolated FGM 
                magnetic field data from C[1-4]_CP_FGM_5VPS products. The spin-axis 
                component of the electric field is calculated with assumption of 
                (E.B) = 0 and with use of 2 electric field 

                components in the spin plane and three magnetic field components.

                
                Data quality description : 
                * 4 : Excellent data which have received special treatment
                * 3 : Good for publication, subject to PI approval
                * 2 : Survey data, not for publication
                * 1 : Known problems, use at your own risk
                * 0 : Bad data
