    The updated guess for the throat Mach number is determined by the following
    equation:

    $$Mth = Mth_0 - \frac{err_0*(Mth_0-Mth_1)}{err_0-err_1}$$

    If the new guess for the throat Mach number is determined to be greater
    than 1, the throat Mach number is set to be equal to 1. Otherwise, the new error
    is determined by recalculating the temperature and area ratios based on
    the new value of <i>Mth</i> and subtracting the area ratios, as done
    previously. If the new e
