        External Email - Use Caution        

For the standard minimum-norm estimate (MNE), the units are Am. Power of
the dSPM-normalized solution, on the other hand, follows an F distribution
(see https://surfer.nmr.mgh.harvard.edu/pub/articles/dale00.pdf).

For eLORETA, I wasn't sure the correct units to use when implementing it,
so I just kept things somewhat normalized -- the units / scale-factor for
that solver are thus arbitrary at present. In theory we should be able to
scale it to provide estimates in Am like MNE, or possibly units of some
statistical distribution like dSPM. (Help welcome if someone knows how!)
