def METHOD_NAME(V_r: ArrayLike) -> NDArrayFloat:
    """
    Define *SMPTE 240M* electro-optical transfer function (EOTF).
    Parameters
    ----------
    V_r
        Video signal level :math:`V_r` driving the reference reproducer
        normalised to the system reference white.
    Returns
    -------
    :class:`numpy.ndarray`
         Light output :math:`L_r` from the reference reproducer normalised to
         the system reference white.
