          Path to the SQD file.

      %(kit_stimthresh)s
      %(preload)s
      %(kit_stimcode)s
      allow_unknown_format : bool
          Force reading old data that is not officially supported. Alternatively,
          read and re-save the data with the KIT MEG Laboratory application.

      %(verbose)s
  
      Returns
      -------
      raw : instance of RawKIT
          A Raw object containing KIT data.
          See :class:`mne.io.Raw` for documentation of attributes and methods.

      Notes
      -----
      ``elp`` and ``hsp`` are usually the exported text files (\*.txt) from the
      Polhemus FastScan system. ``hsp`` refers to the headshape surface points.
      ``elp`` refers to the points in head-space that corresponds to the HPI
      points.
  
      If ``mrk``\, ``hsp`` or ``elp`` are :term:`array_like` inputs, then the
      numbers in xyz coordinates should be in units of meters.
