         The ``"prominence"`` method might be useful to detect the waves, allowing to set individual physiological
         limits (see kwargs), while the ``"dwt"`` method might be more precise for detecting the onsets and offsets
         of the waves (but might exhibit lower accuracy when there is significant variation in wave morphology).
