Compute orientation prior.
float| ‘auto’ |
Value that weights the source variances of the dipole components that are parallel (tangential) to the cortical surface. Can be:
If 0, then the solution is computed with fixed orientation. If 1, it corresponds to free orientations.
Uses 0.2 for surface source spaces (unless
fixed is True) and
1.0 for other source spaces (volume or mixed).
Mapping from the key for a given source space type (surface, volume, discrete) to the loose value. Useful mostly for mixed source spaces.
