[FieldTrip] MEG gradiometer leadfield units

[HINDRIKS, RIKKERT]

Hi all,

I constructed a single-sphere leadfield in Fieldtrip for the CTF 275 MEG
system,
but am unsure about the units:

If I assume that dipole moments are expressed in pAm and sensor signals in
T,
then a dipole moment of 10 nAm gives sensor signals in the range 10-100 fT,
which is what one expects.

Can anyone confirm the units I assumed for this leadfield?

Thanks a lot,
Rikkert Hindriks
