def epsilon_Tee_Gotoh_Steward_2(Tc, omega):
    """Calculates Lennard-Jones depth of potential-energy minimum.
    Uses critical temperature and acentric factor. CSP method by [1]_.

    .. math::
        \\epsilon/k = (0.7915 + 0.1693 \\omega)T_c

    Parameters
    ----------
    Tc : float
        Critical temperature of fluid [K]
    omega : float
        Acentric factor for fluid, [-]

    Returns
    -------
    epsilon_k : float
        Lennard-Jones depth of potential-energy minimum over k, [K]

    Notes
    -----
    Further regressions with other parameters were performed in [1]_ but are
    not included here, except for `epsilon_Tee_Gotoh_Steward_1`.

    Examples
    --------
