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)..

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)..

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..
