File Description
File Name: rbsp-?_magnetometer_4sec-gsm_emfisis-L2_<YYYYmmdd>_<version>.cdf
Variables:
Epoch: TT2000 epoch, nanoseconds since 2000 of the record.
Mag: 3 elements of the mag vector (nT) in GSM coordinates (Mag X, Mag Y, Mag Z).
Magnitude: Absolute magnitude of magnetic field (Square root of the sum of the squares), in nT.
delta: Angle (degrees) of the vector off of the XY plane; in the fashion as Latitude
lambda: Angle (degrees) of the vector projected in the XY (0 is along the X 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.
partition: SUPPORT DATA. Partition for the SPICE Kernel used.
calState: SUPPORT DATA. Calibrator signal active status, 0 - Calibration off, 1 - Calibration on. Data is not scientifically valid when the calibration is active.
magInvalid: SUPPORT DATA. Indicator of invalid data. 0 - Valid data, 1 - Invalid data. USE INVALID DATA WITH EXTREME CAUTION!
magFill: SUPPORT DATA. Indicator of fill data. 0 - Valid data, 1 - Fill data used. Data is occationaly filled where a data gap exists. DO NOT USE FILL DATA FOR SCIENTIFIC PURPOSES!
coordinates: Vector location of the spacecraft in GSM coordinate system.
rms: RMS value for the 1 second period
