class_docstr: Dipole class for fixed-position dipole fits.
  
  .. note::
      This class should usually not be instantiated directly
      via ``mne.DipoleFixed(...)``. Instead, use one of the functions
      listed in the See Also section below.
  
  Parameters
  ----------
  %(info_not_none)s
  data : array, shape (n_channels, n_times)
      The dipole data.
  times : array, shape (n_times,)
      The time points.
  nave : int
      Number of averages.
  aspect_kind : int
      The kind of data.
  comment : str
      The dipole comment.
  %(verbose)s
  
  See Also
  --------
  read_dipole
  Dipole
  fit_dipole
  
  Notes
  -----
  This class is for fixed-position dipole fits, where the position
  (and maybe orientation) is static over time. For sequential dipole fits,
  where the position can change a function of time, use :class:`mne.Dipole`.
