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.
Error Flags : Value of zero signifies no quality errors.
For non-zero values:
* Bit-0 = manually flagged interval
* Bit-1 = overcounting/saturation effects likely present in skymap
* Bit-2 = reported spacecraft potential above 20V
* Bit-3 = invalid/unavailable spacecraft potential
* Bit-4 = significant (greater than 10%) cold plasma (greater than 10eV) component
* Bit-5 = significant (greater than 25%) hot plasma (greater than 30keV) component
* Bit-6 = high sonic Mach number (v/vth greater than 2.5)
* Bit-7 = low calculated density (n_DIS lower than 0.0 cm^-3)
* Bit-8 = bentPipe magnetic field used instead of brst l2pre magnetic field
* Bit-9 = srvy l2pre magnetic field used instead of brst l2pre magnetic field
* Bit-10 = no internally generated photoelectron correction applied
* Bit-11 = compression pipeline error
* Bit-12 = spintone calculation error (DBCS only)
* Bit-13 = significant (greater than 20%) penetrating radiation
