Load the MEG helmet associated with the MEG sensors.

Parameters

infoinstance of Info: Measurement info.
transdict: The head<->MRI transformation, usually obtained using read_trans(). Can be None, in which case the surface will be in head coordinates instead of MRI coordinates.
verbosebool, str, int, or None: If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

Returns

surfdict: The MEG helmet as a surface.

Notes

A built-in helmet is loaded if possible. If not, a helmet surface will be approximated based on the sensor locations.
