The data is provided in units of phase space density. The reference frame is related to the instrument frame, and is called near-GSE. For more information on the FPI instruments, data set, and user guide, please see: MMS Science Data Center (https://lasp.colorado.edu/mms/sdc/public/datasets/fpi/) MMS FPI Data Users and Products Guide (https://lasp.colorado.edu/galaxy/display/MFDPG/MMS+FPI+Data+Users+and+Products+Guide) FPI Release Notes (https://lasp.colorado.edu/mms/sdc/public/datasets/fpi/mms-FPIReleaseNotes-220217.pdf) FPI data, as a data set of the MMS-SMART data products, are open to all scientists and the public (Users). Users should contact the MMS-SMART Principal Investigator (PI) J. L. Burch and B. Giles the FPI Lead to consult on the appropriate use of instrument data. Users should acknowledge the sources of data used in all publications, presentations, and reports. Please send information on the use of these data to: PI: J. L. Burch [jburch@swri.edu] FPI Lead: B. Giles [barbara.giles@gsfc.nasa.gov] We suggest to add the following lines into the acknowledgments: The authors acknowledge NASA, CNES (Centre National d'Etudes Spatiales) and CNRS (Centre National de la Recherche Scientifique) for their support to the MMS/FPI team and the CDPP (Centre de Données de la Physique des Plasmas) for the distribution of the MMS/SCM data. and if PI/coI are not part of the publication list, then we suggest to add Specifically, we acknowledge J. L. Burch for use of data from the MMS-SMART mission, B. Giles for use of FPI data.
