Calculations of the diffusivity factor using a canned routine (“exact”) vs. those performed using our fitting formulae for ﹩{{ \mathcal E }}_{1}﹩ in Equation (21) (“approximate”). The calculation labeled “fit” is a 13th order polynomial fit to the exact solution, which performs poorly even at the ﹩\sim {10}^{-3}﹩ level.
