        "Description": "The Spin-plane Double Probe (SDP) and the Axial Double Probe (ADP) instruments are part of the \nFIELDS instrument suite of the Magnetospheric Multiscale mission (MMS). The combination of SDP \nand ADP is referred to as the Electric field Double Probe (EDP) instrument. EDP measures the 3-D \nelectric field with an accuracy of 0.5 mV/m over the frequency range from DC to 100 kHz. SDP \nconsists of 4 biased spherical probes extended on 60 m long wire booms 90° apart in the spin plane, \ngiving a 120 m baseline for each of the two spin-plane electric field components. ADP consists of 2 \nbiased cylindrical probes extended on ~12 m long stiff booms along the spacecraft axis, giving a 29.2 \nm baseline for the axial electric field component.",
