            <Description> Electric Field in ISR2 is obtained from CAA C[1-4]_CP_EFW_L3_E 
                
                The EFW instrument measures the electric field only in the spacecraft 
                spin plane, therefore a spin-plane oriented coordinate system is best suited for scientific studies involving the electric field. The ISR2 (Inverted Spin Reference) system, also known as DSI (Despun System Inverted), is such a system. The X and Y axes are in the spin plane, with X pointing as near sunward as possible and Y perpendicular to the sunward direction, positive towards dusk. The Z-axis is along the (negative) spacecraft spin axis, towards the north ecliptic. The coordinate system is called Inverted because the actual spin axis of Cluster is pointing towards the south ecliptic. The difference between ISR2 (DSI) and the GSE (Geocentric Solar Ecliptic) is a tilt of 2° to 7° of the Z-axis performed in order
                to avoid shading of the EFW probes by the spacecraft.</Description>
