      <Description>The magnetometer (MAG) on MESSENGER is a three-axis 
ring core fluxgate magnetometer mounted on a 3.6 m boom in the anti-
sunward direction.  The detector sampling rate is 40 Hz and readout 
rates are selectable from 0.01, 0.1, 1, 10, 20, or 40 Hz. Averaging 
intervals can be selected from 0.025 to 1 s. Digital filters provide 
selectable bandpassed channels of magnetic field variation.</Description>
