Description
This data set contains the Cluster EFW Summary Parameters (one minute averaged). The parameters are two status parameters and six data parameters.
Caveats
The CSDS data are intended for event identification and are not for publication. Some obviously incorrect data have been removed in the validation process, but there may still be occasional data with poor quality in the PPDB and SPDB. Please always contact the EFW PI or the CSDS file validator (information given in the global attributes of each CDF file) for questions on data validity.
The electric field E_dusk has not been corrected for offsets present due to, e.g., photoelectron asymmetries.
The parameter U_probe_sc can be used as an approximate indicator of the electron density, except during periods when ASPOC is operating. Such periods have not been removed from the data. A more (less) negative value of U_probe_sc indicates lower (higher) density.
The operation of WHISPER in the active mode sometimes disturbs the EFW measurements. Such disturbed data have most likely been removed in all quantities except U_probe_sc, where the disturbance is least severe.
