meg_wiki.calibration.load_fine_calibration(fname)🔗

Load a fine calibration.

The fine calibration typically includes improved sensor locations, calibration coefficients, and gradiometer imbalance information.

Parameters:
fnamepath-like

Path to the '.dat' file containing the mapping to load. Each line yields one channels formatted.

Returns:
calibrationdict

Fine calibration information.

  • ch_nameslist of str

    List of the channel names.

  • locsarray of shape (n_channels, 12)

    Coil location and orientation parameters.

  • imb_calslist of array of shape (1,) or (3,)

    For magnetometers, the calibration coefficients. For gradiometers, one or three imbalance parameters.
