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 in this mode. Data are also made
available at survey (4.5 s) resolution. Per mission design, not all burst-resolution data are downlinked, but all sur vey data are downlinked. Planning around calibration activities, avoidance of Earth radiation belts, etc, when possible
, FPI usually operates in Slow Survey (SS) Mode (60 s resolution) outside of ROI. This moments 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 in
dicated time.
