 <li><code>null_weights</code> activates nullification of the nonlinear WENO weights at the buffer regions outside the domain boundaries when the Riemann extrapolation boundary condition is specified (<code>bc_[x,y,z]%beg[end]} = -4</code>).</li>
 <li><code>mp_weno</code> activates monotonicity preservation in the WENO reconstruction (MPWENO) such that the values of reconstructed variables do not reside outside the range spanned by WENO stencil (<a href="references.md#Balsara00">Balsara and Shu, 2000</a>; <a href="references.md#Suresh97">Suresh and Huynh, 1997</a>).</li>
 <li><code>riemann_solver</code> specifies the choice of the Riemann solver that is used in simulation by an integer from 1 through 3. <code>riemann_solver = 1</code>, <code>2</code>, and <code>3</code> correspond to HLL, HLLC, and Exact Riemann solver, respectively (<a href="references.md#Toro13">Toro, 2013</a>).</li>
-<li><code>low_Mach</code> specifies the choice of the low Mach number correction scheme for the HLLC Riemann solver. <code>low_Mach = 0</code> is default value and does not apply any correction scheme. <code>low_Mach = 1</code> and <code>2</code> apply the anti-dissipation pressure correction method (<a href="references.md#Chen22">Chen et al., 2022</a>) and the improved velocity reconstruction method (<a href="reference.md#Thornber08">Thornber et al., 2008</a>). This feature requires <code>riemann_solver = 2</code> and <code>model_eqns = 2</code>.</li>

 <li><code>avg_state</code> specifies the choice of the method to compute averaged variables at the cell-boundaries from the left and the right states in the Riemann solver by an integer of 1 or 2. <code>avg_state = 1</code> and <code>2</code> correspond to Roe- and arithmetic averages, respectively.</li>
 <li><code>wave_speeds</code> specifies the choice of the method to compute the left, right, and middle wave speeds in the Riemann solver by an integer of 1 and 2. <code>wave_speeds = 1</code> and <code>2</code> correspond to the direct method (<a href="references.md#Batten97">Batten et al., 1997</a>), and indirect method that approximates the pressures and velocity (<a href="references.md#Toro13">Toro, 2013</a>), respectively.</li>
 <li><code>weno_Re_flux</code> activates the scaler divergence theorem in computing the velocity gradients using WENO-reconstructed cell boundary values. If this option is false, velocity gradient is computed using finite difference scheme of order 2 which is independent of the WENO order.</li>
