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.
