Cluster 4 EDI Prime Parameters

ResourceID
spase://CNES/NumericalData/CDPP-Archive/Cluster-4/EDI/CLU_PP_C4_EDI

Description
This data set contains the Cluster 4 EDI Prime Parameters. Those parameters are the 3 components of the electron drift velocity and the 3 components of the electric field (cartesian components, GSE coordinates, corrected for spacecraft motion), the instrument status and a Reduced chi-squared variable which is a floating point scalar. Caveats The measured electron drift velocity cannot always be separated into the electric-field and magnetic-gradient induced parts. In such cases the computed electric fields are subject to contamination by magnetic gradient effects. The data quality is variable, and it is therefore mandatory that the status bytes be consulted before interpreting the data. The number of samples in the averages is variable.
