In this paper:
Ahlfors, Seppo P., et al. "Sensitivity of MEG and EEG to source
orientation." \*Brain topography\* 23.3 (2010): 227-232.?
They compured the sensitivity map for 3 orthogonal orientation at each
location,
1) I think the sensitivity map in MNE is same as the paper?
2) in below you put see manual, which manual?
3) what I should use a mode to make the computation for 3 orthogonal
direction of the source?
\*mode\*str \<[https://docs.python.org/3/library/stdtypes.html#str](https://docs.python.org/3/library/stdtypes.html#str)\>
The type of sensitivity map computed. See manual. Should be ?free?,
?fixed?, ?ratio?, ?radiality?, ?angle?, ?remaining?, or ?dampening?
corresponding to the argument ?map 1, 2, 3, 4, 5, 6 and 7 of the command
mne\_sensitivity\_map.

see how it's computed
[https://github.com/mne-tools/mne-python/blob/master/mne/proj.py#L331:5](https://github.com/mne-tools/mne-python/blob/master/mne/proj.py#L331:5)
this suggests me that some reference to literature are missing in the docstrings
it would be great to fix this.
