Parameters ---------- evoked : instance of Evoked The evoked object to use for CSS. Must contain magnetometer, gradiometer, and EEG channels. %(picks_good_data)s mag_picks : array-like of int Array of the magnetometer channel indices that will be used to find the reference data. If None (default), all magnetometers will be used. grad_picks : array-like of int Array of the gradiometer channel indices that will be used to find the reference data. If None (default), all gradiometers will be used. n_proj : int The number of projection vectors. %(verbose)s Returns ------- evoked_subcortical : instance of Evoked The evoked object with cortical contributions to the EEG data suppressed. Notes ----- This method removes the common signal subspace between the magnetometer data and the gradiometer data from the EEG data. This is done by a temporal projection using ``n_proj`` number of projection vectors. For reference, see :footcite:`Samuelsson2019`.
