``BOUNDARY_MODEL``

    Boundary model type:
    0. Lower WENO order (stable)
    1. Zero weights (unstable for small :math:`D_{\mathrm{ax}}`)
    2. Zero weights for :math:`p \neq 0` (stable?)
    3. Large ghost points

    =============  ===========================  =============

``WENO_ORDER``

   WENO order, also called WENO :math:`k`:
