raw : Raw object 
 
inverse_operator : dict 
Inverse operator returned from mne.read_inverse_operator,
prepare_inverse_operator or make_inverse_operator. 
 
lambda2 : float 
The regularization parameter. 
 
method : “MNE” | “dSPM” | “sLORETA” 
Use mininum norm, dSPM or sLORETA. 
 
label : Label | None 
Restricts the source estimates to a given label. If None,
source estimates will be computed for the entire source space. 
 
start : int 
Index of first time sample (index not time is seconds). 
 
stop : int 
Index of first time sample not to include (index not time is seconds). 
 
nave : int 
Number of averages used to regularize the solution.
Set to 1 on raw data. 
 
time_func : callable 
Linear function applied to sensor space time series. 
 
pick_ori : None | “normal” 
If “normal”, rather than pooling the orientations by taking the norm,
only the radial component is kept. This is only implemented
when working with loose orientations. 
 
buffer_size : int (or None) 
If not None, the computation of the inverse and the combination of the
current components is performed in segments of length buffer_size
samples. While slightly slower, this is useful for long datasets as it
reduces the memory requirements by approx. a factor of 3 (assuming
buffer_size << data length).
Note that this setting has no effect for fixed-orientation inverse
operators. 
 
prepared : bool 
If True, do not call prepare_inverse_operator. 
 
verbose : bool, str, int, or None
