Magnetometer UVW


Standard Survey Product            

Three Axis DC Magnetic field vector in the UVW science coordinate system.   UVW is the spacraft science coordinate system where W is along the spin axis.  THIS IS A SPINNING COORDINATE SYSTEM.  Data is orthogonalized

Mag U, Mag V, Mag W

Units:  nT,  nT,  nT 

Cadence: 1 vector every 0.015625 seconds (64 samples per second)

File Description

File Name: rbsp-?_magnetometer_uvw_emfisis-L2_<YYYYmmdd>_<version>.cdf


Epoch: TT2000 epoch, nanoseconds since 2000 of the record.

Mag:  3 elements of the mag vector in UVW coordinates (MagU, MagV, MagW).  

Magnitude: Absolute magnitude of magnetic field (Square root of the sum of the squares)

delta:  Angle of the vector off of the spin plane  (W) ; in the fashion as Latitude

lambda: Angle of the vector projected in the spin plane (0 is along the U axis) ; in the fashion as Longitude

range_flag: SUPPORT DATA. Indicator of the active range the sensor; 0 - Range 0 (+/- 256 nT), 1 - Range 1 (+/- 4096 nT), 3 - Range 3 (+/- 65536 nT)

MET:  SUPPORT DATA. Mission Elapsed Time of the data.  

calState: SUPPORT DATA. Calibrator signal active status, 0 - Calibration off, 1 - Calibration on. Data is not scientifically valid when the calibration is active.
