ORCF lattice has variation ORCF2 when :math:`\dfrac{1}{a^2} < \dfrac{1}{b^2} + \dfrac{1}{c^2}`. Cell constructor ================ To get an example of the cell use :py:func:`wulfric.cell.SC_ORCF`. :py:func:`wulfric.cell.sc_get_example` returns an example where :math:`a = 1.2\pi`, :math:`b = 5\pi/4` and :math:`c = 5\pi/3`. ..
