 error in the function and its first several derivatives appears to trend
 towards zero exponentially in the polynomial order $n$.
 
+Even at $n=2$, where only six unknown parameters have been fit, the results are
+accurate to within $2\times10^{-3}$. This approximation for the scaling functions also captures the singularities at the high- and low-temperature zero-field points well.
