Parameter #6
Name
EFW BEB Configuration
ParameterKey
e_hires_uvw_BEB_config
Description
EFW Boom Electronics Board (BEB) configuration code (on-board sensor biases
Caveats
Indicates the configuration of the EFW Boom Electronics Board (BEB). Encodes the following information: for each sensor, sensor current bias, usher and guard voltage bias. See EFW-FAQ (http://rbsp.space.umn.edu/efw_faq.html) for a detailed description of the mapping between code value and instrument configuration (not crucial for L2 data interpretation)..

ParameterKey
e_hires_uvw_DFB_config
Description
EFW Digital Fields Board (DFB) Configuration code (on-board spectral and waveform processing configuration)
Caveats
Indicates the configuration of the EFW Digital Filter Board (DFB). Encodes the following information: assignment of analog input channels to the various on-board spectral processors (FBK, SPEC, XSPEC); parameters of the on-board B-field-aligned data processing; nominal or contingency multiplexer programming. See EFW-FAQ (http://rbsp.space.umn.edu/efw_faq.html) for a detailed description of the mapping from code value to instrument configuration (not crucial for L2 data interpretation)..

Description
Timetags for elements of efw_qual.
Caveats
The elements of efw_qual are determined on a fixed cadence regardless of the nominal cadence of the individual L2 data products, and epoch_qual provides storage for those fixed-cadence time tags..

EFW Data Quality Flags
ParameterKey
e_hires_uvw_efw_qual
Description
EFW quality array (global estimate of EFW data quality, plus 13 underlying observatory and instrument-level data quality factors)
Caveats
The quality of EFW data products can be affected by a variety of observatory and instrument-level conditions. efw_qual is a collection of flags that show the estimate of each of these contributors over time. ..See the EFW-FAQ (http://rbsp.space.umn.edu/efw_faq.html) for a detailed description of the determination and meaning of each of the elements of efw_qual...If the value of a particular element of efw_qual is not relevant to the quality of a particular data product, it shall receive the value EFW_QUAL_NR (typ. -2)...If the value of a particular element of efw_qual is relevant to the quality of a particular data product but is not known at the time lf L2 data production, it shall receive the value EFW_QUAL_DUNNO (typ. -1)...A quality value of EFW_QUAL_GOOD (typ. 0) indicates that there are no known issues with the data product due to that particular element of efw_qual...The quality values are meant to be conservative, and values other than EFW_QUAL_GOOD should lead the user back to a member of the EFW instrument team for discussion and advice on the nature of the data quality as needed..
