        "Description": "The Digital Ion Drift Meter was provided by\nthe Air Force Research Laboratory, Hanscom AFB, USA.  It determines\nion distributions and moments (density, temperature, drift\nvelocity) and can be used in computing V x B electric fields.\nThere is a companion Planar Langmuir Probe used for spacecraft\npotential and electron density and temperature determinations.\nThe DIDM and PLP data are used to help separate internal-source\nand external-source magnetic field variations, the former being \na primary focus of the mission.",
