-* ``str1`` is the type of scaling to use for the CFS :math:`\alpha` parameter. It can be ``constant``, ``linear``, ``quadratic``, ``cubic``, and ``quartic``.
+* ``str1`` is the type of scaling to use for the CFS :math:`\alpha` parameter. It can be ``constant``, ``linear``, ``quadratic``, ``cubic``, ``quartic``, ``quintic``and ``sextic``.
 * ``str2`` is the direction of the scaling to use for the CFS :math:`\alpha` parameter. It can be ``forward`` or ``reverse``.
 * ``f1 f2`` are the minimum and maximum values for the CFS :math:`\alpha` parameter.
-* ``str3`` is the type of scaling to use for the CFS :math:`\kappa` parameter. It can be ``constant``, ``linear``, ``quadratic``, ``cubic``, and ``quartic``.
+* ``str3`` is the type of scaling to use for the CFS :math:`\kappa` parameter. It can be ``constant``, ``linear``, ``quadratic``, ``cubic``, ``quartic``, ``quintic``and ``sextic``.
 * ``str4`` is the direction of the scaling to use for the CFS :math:`\kappa` parameter. It can be ``forward`` or ``reverse``.
 * ``f3 f4`` are the minimum and maximum values for the CFS :math:`\kappa` parameter. The minimum value for the CFS :math:`\kappa` parameter is one.
-* ``str5`` is the type of scaling to use for the CFS :math:`\sigma` parameter. It can be ``constant``, ``linear``, ``quadratic``, ``cubic``, and ``quartic``.
+* ``str5`` is the type of scaling to use for the CFS :math:`\sigma` parameter. It can be ``constant``, ``linear``, ``quadratic``, ``cubic``, ``quartic``, ``quintic``and ``sextic``.
