good to know

> but the problem is that one source could have a completely different orientation in each of the time-frequency windows if we allow max-power. Of course it can still have if we do None, but to me if you use free orientation you're not really interested in orientation? Dalal says they enforce the same orientation between the active and control data, but I'm not sure if they do for all the t-f windows, but that would seem the proper thing to do.

I would let the orientation change at each time window. It's like a
rotating dipole model.
But indeed it must be the same between conditions.

ok good

when you're done I'll give a last round of reviews tomorrow.
