Create an ad hoc noise covariance.
mne.Info
The mne.Info
object with information about the sensors and methods of measurement.
dict
of float
| None
Standard_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
| None
Control 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.
Covariance
The 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.
