In the reference publication :footcite:`Samuelsson2019`,48    the joint subspace between magnetometers and gradiometers is used to49    suppress the cortical signal in the EEG data. In principle, other50    combinations of sensor types (or channels) could be used to suppress51    signals from other sources.52 53    References54    ----------55    .. footbibliography::56    �evokedr
