Create an ad hoc noise covariance.
mne.InfoThe mne.Info object with information about the sensors and methods of measurement.
dict of float | NoneStandard_deviation of the diagonal elements. If dict, keys should be
'grad' for gradiometers, 'mag' for magnetometers and 'eeg'
for EEG channels. If None, default values will be used (see Notes).
str | int | NoneControl verbosity of the logging output. If None, use the default
verbosity level. See the logging documentation and
mne.verbose() for details. Should only be passed as a keyword
argument.
CovarianceThe ad hoc diagonal noise covariance for the M/EEG data channels.
Notes
The default noise values are 5 fT/cm, 20 fT, and 0.2 µV for gradiometers, magnetometers, and EEG channels respectively.
