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. Planning around Calibration Activities, avoidance of Earth Radiation Belts, etc., when possible, FPI usually Operates in Slow Survey (SS) Mode outside of ROI, and then only the 60 s Resolution Survey Data are available. This Product contains Results from integrating the standard Moments of Phase Space Distributions formed from the indicated Data Type (DES/DIS Burst, FS or SS). For Convenience, some additional Parameters are included to augment those most commonly found in a Moments Product of this sort, plus 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-MOMS 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: 8731, and CDF Skeleton Version Revision Date: 2018-07-10T12:19:56.
