-
mne.make_ad_hoc_cov(info, std=None, verbose=None)[source]¶ Create an ad hoc noise covariance.
- Parameters
- infoinstance of
Info Measurement info.
- std
dictoffloat|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).
- verbosebool,
str,int, orNone If not None, override default verbose level (see
mne.verbose()and Logging documentation for more).

- Returns
- covinstance of
Covariance The ad hoc diagonal noise covariance for the M/EEG data channels.
- covinstance of
Notes
The default noise values are 5 fT/cm, 20 fT, and 0.2 uV for gradiometers, magnetometers, and EEG channels respectively.
New in version 0.9.0.
