        "Description": "Each Cluster spacecraft carries an identical FGM instrument(Fluxgate Magnetometer) to measure the DC magnetic fieldvector. Each instrument, in turn, consists of two triaxialfluxgate magnetometers and an onboard data processing unit.The instrument samples the magnetic field at a cadence of 22 Hz(67 Hz in Burst mode). In order to minimise the magnetic background of the spacecraft, one of the magnetometer sensors (the outboard, or OB sensor) is located at the end of one of the two 5 m radial booms of the spacecraft, the other (the inboard, or IB sensor) at 1.5 m inboard from the end of the boom. Since the start of the scientific operations on February 1, 2001, only the outboard sensor on each satellite has been used.",
