Double Star 2 LEID Prime Parameters

ResourceID
spase://CNES/NumericalData/CDPP-Archive/DoubleStar2/LEID/DSTAR_PP_T2_LEI

Description
The Low Energy Ion Detector (LEID) is present on the polar spacecraft (Double Star 2) only. The instrument performs measurements of the energy spectrum, the velocity distribution function and the differential flux of low energy ions in the polar regions. This data sets contains Double Star 2 LEID prime parameters at spin resolution. These parameters include the instrument status and several moments (ion density and velocity, and parallel and perpendicular ion temperature).
