source_induced_power: order of the steps power calculation/source reconstruction

Dear all,

I would like to know if the
mne.minimum_norm.time_frequency.source_induced_power function is doing the
power/PLV calculation before or after the source reconstruction. It's not
clear to me when I have a look on the github code...

Thanks a lot,
Laetitia Grabot.

The function name is meant to indicate that the measure operates in source
space. IIRC the code may look confusing because the frequency coefficients
are calculated in sensor space and projected into source space. This
technique is used to give an equivalent result with reduced computation
time.
