X-axis magnetic field

The magnetic field in each of the three orthogonal directions is computed from the corresponding coil's digitized value and the magnetic field scaling factor. The magnetic field in milligauss units is computed by first adding 0.5 to the digitized value and then multiplying by the appropriate scaling factor (see the magnetic field scale attribute).

DOMAIN

The magnetic field is a positive floating point number. Using the scaling factors provided, the units of measure are milligauss. The minimum field recordable by the EMDEX along a single axis is 0.05 milligauss. The maximum field is 25,550 milligauss.
