Description

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.

Caveats
This SPASE Numerical Data Description is for the MMS2_FPI_FAST_L2_DES-DIST Data Product. This Numerical Data Description has been written by utilizing the ADAPT Software Package. ADAPT can harvest Metadata that are embedded in Data Files stored in Common Data File Format that are then leveraged to populate corresponding SPASE Schema Text Fields. Typically, the CDF embedded Metadata are harvested from CDF Master Files, which contain no actual Data, in order to populate SPASE Documents. In this case, the Metadata were harvested from a "Data" CDF, which contains actual Data Observations from one of the four MMS FPI Instruments. The "Data" CDF used by ADAPT has the following Specifications: Data Product Version Number: 3.3.0, CDF Generation Date: 2018-11-02T19:05:20, CDF Skeleton Version Revision Number: 8026, and CDF Skeleton Version Revision Date: 2017-05-26T15:45:00.

Azimuth Bin: Sector Index=00 looks "after" (Spin Phase) the Sun Direction, ..., Sector Index=31 looks "before" the Sun Direction. Head Field of View: Pixel Index=00 looks to Zenith, ..., Pixel Index=15 looks to Nadir. FPI Operations nominally bin Data from 64 Energy Filters into 32 pairwise Energy Bins, indexed 00-31. Nominally, Bins are indexed in increasing Energy Order. See the FPI Documents for Details.

Caveats
Azimuth Bin: Sector Index=00 looks "after" (Spin Phase) the Sun Direction, ..., Sector Index=31 looks "before" the Sun Direction. Head Field of View: Pixel Index=00 looks to Zenith, ..., Pixel Index=15 looks to Nadir. FPI Operations nominally bin Data from 64 Energy Filters into 32 pairwise Energy Bins, indexed 00-31. Nominally, Bins are indexed in increasing Energy Order. See the FPI Documents for Details.
