      <Description>The IES is a plasma instrument consisting of two electrostatic analyzers, one each for electrons and ions. In general, IES acquires ion and electron measurements in 256 bins over an azimuth range of 90 degrees and polar angle of 360 degrees (less spacecraft obstructions). Thus IES collects plasma data roughly in 2.8 π steradians of space, and samples plasma velocity space.</Description>
