MMS 2 Fast Plasma Investigation, Dual Electron Spectrometer (FPI, DES) Instrument Distributions, Level 2 (L2), Fast Mode, 4.5 s Data

Published by MMS Science Data Center;NASA Space Physics Data Facility (SPDF) Coordinated Data Analysis Web (CDAWeb) Data Services | National Aeronautics and Space Administration | Metadata Last Checked: February 21, 2026 | Last Modified: 2026-02-16
The Fast Plasma Instrument (FPI) usually Operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at Burst (30/150 ms for DES/DIS) Resolution are aggregated onboard and made available at Survey (4.5 s) Resolution in this Mode. This Product contains Phase Space Distribution Maps of Results from surveying the High Resolution Observations during each 4.5 s Period. In particular, the (highest possible Quality at the Time of Release) corrected/converted "Fast Survey Sky Map" Distributions are reported with Time Stamps and other Annotation characterizing the State of the Instrument System at the indicated Time.
