(*)From the FGM Data Products Guide:

Quicklook data have the best available calibration at the time of downlink applied and are not intended for scientific analysis.

Quicklook provides time series plots in .png format of FGM data, which is derived from either DFG or AFG.

Magnetic field data is provided in Despun Major Principal Axis of inertia (DMPA) coordinates, which is considered to be a ‘near-GSE’ coordinate system. That is, no attitude data has been applied, other than to despin using the on-board sun pulse times. The DMPA Z-axis is the aligned with the Major Principal Axis (MPA). In nominal operations, the MPA is maintained to be within 3 degrees of the GSE Z-axis (ecliptic normal). Thus, within the Region of Interest (ROI), DMPA should be within 3 degrees of alignment with true GSE coordinates. The MPA can
be assumed to fixed in inertial space and aligned with the Angular Momentum vector, except in the presence of nutation. For the first year since launch, nutation has been observed to be minimal, and generally damped within hours after spacecraft maneuvers.
In addition, a GSE to GSM transformation is applied to the DMPA data to yield data in what is termed GSM-DMPA coordinates. For a formal discussion of coordinate systems, see the MMS Project Coordinate System and Alignment Document (461-SYS-SPEC-0115C, or most recent version).

title: Gold Level 1D Occultation Plots

description: The Level 1C Dayside Disk Images are interrupted via stored instrument commands when 
	  target stars suitable for occultation measurements approach either limb. 
	  To perform the occultation measurement, the slit mechanism inserts the 1 degree wide occultation (OCC) 
	  slit at the spectrometer focal plane, and the scan mirrors slew the Field of View to the star. 
	  The mirror is centered at a 225 km tangent point altitude. Occultations require 6 minutes to 
	  execute (30 seconds to configure the instrument, 30 seconds for uncertainty in timing and pointing, 
	  4 minutes for the actual occultation, 30 seconds for uncertainty in timing and pointing, and 30 
	  seconds to return to HR slit). Once the occultation is complete, the HR slit is inserted, the scan 
	  mirror returns to its departure point in the original mapping observation. By choice GOLD is limited 
	  to performing ~10 occultations a day for most of the year, 
	  reducing the dayside mapping duty cycle by ~5%.
