      <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.. </Caveats>
