Bob,
The correct units for all the FFT MAGMAP filters are "ground units" (i.e.
the survey ground units used in your grid e.g.. metre, feet etc.).
In your case the nt/m should be nt/ground_unit.
The GX help documents have been modified for v4.3 to resolve this issue.

Subject: [geonet]: Derivative Units out of FFT MAGMAP
I noticed the units for derivative operations listed in the MAGMAP
documentation are nt/m. Is this really true or is it nt/grid spacing where
grid spacing could be 100 whatevers?
