    33533353In general, for multiples of the minimal depth $N H_0$ one obtains
    3354 \[
     3354\begin{equation}
    33553355  \left[ \frac{\mu}{h + h_0/h} \right]_{h = N H_0} =
    3356   \frac{\mu}{H_0 (1 + 1/N^2)}
    3357 \]
     3356  \frac{\mu}{N H_0 + H_0/N} = 
     3357  \frac{\mu}{h (1 + 1/N^2)}
     3358  \label{eq:flux limit multiple}
     3359\end{equation}
    33583360which converges quadratically to the true value with the multiple N.

     3362Although this equation can be used for any depth, we have restricted its use to depths less than $10 * H_0$ (or 1 cm) to computational resources.
     3363According to Equation \ref{eq:flux limit multiple} this cutoff   
     3364affects the calculated velocity by less than 1 \%.
