    Next, the script determines the ideal gas constant, <i>R</i>, and the specific
    heat ratio, &gamma;, by using a table-lookup method. The heat capacity, <i>Cp</i>,
    is determined by the following equation:

    $$Cp = \frac{R*\gamma}{\gamma-1}$$

    The static pressure at the exit plane (<i>Pe</i>) is determined by
    utilizing an additional script (calc_Pstatic.c), which calculates the
    static pressure using the secant method. The
