[CDAWeb List/Download/Create ONLY] MMS4 FPI/DES burst sky-map instrument distribution

Az bin: sector ind=00 looks "after" (spin-phase) Sun, ..., sector ind=31 looks "before" Sun dir.  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 0-31.  Nominally, bins are indexed in increasing energy order.  See FPI docs for details.

[List/Create only in CDAWeb] 1-sigma error: MMS4 FPI/DES burst sky-map instrument distribution

MMS4 FPI/DES vector of data-quality indicators at burst-start time

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

---> MMS4 FPI/DES compression lossless/lossy indicator at survey-start time

FPI/DES alternates between two tables, designated "even" (0) and "odd" (1).

---> MMS4 FPI/DES Del-Phi (obs spin-phase) count at burst-start time

Nominally, spin-phase counts range over [0000, 5759] cnts.  Each count represents 1/16 deg of observatory spin-phase.  Zero spin-phase count indicates obs +X-axis aligned with Sun.

---> MMS4 FPI/DES Del-Phi (obs spin-phase) angle at burst-start time

Nominally, spin-phase angles range over [0, 360) deg.  Each count represents 1/16 deg of observatory spin-phase.  Zero spin-phase angle indicates obs +X-axis aligned with Sun.

Az bin: sector ind=00 looks "after" (spin-phase) Sun, ..., sector ind=31 looks "before" Sun dir.  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 0-31.  Nominally, bins are indexed in increasing energy order. Offsets reflect 128 steps over the 30 msec sweep period. See FPI docs for details.

Records P-value used to de-spin this burst sky-map on board.  See FPI docs for details.

Azimuth bin: sector index=00 looks "after" (spin-phase) Sun, ..., sector index=31 looks "before" Sun dir.

Azimuth bin: "sector00" looks after Sun, ..., "sector31" looks before Sun dir.

Head field-of-view: pixel index=00 looks to zenith, ..., pixel index=15 looks to nadir.

Head field-of-view: "pixel00" looks to zenith, ..., "pixel15" looks to nadir.

FPI operations nominally bin data from 64 energy filters into 32 pairwise energy bins, indexed 0-31.  Nominally, bins are indexed in increasing energy order.  See FPI docs for details.

Note that the deltas are provided to indicate that FPI is reporting the energy bin centers. These do not necessarily reflect the energy bandwidth that is sampled by FPI at a given energy step.
