 In the first form (in the center of the equation), $\frac
-1{2 \cdot 1.6}$ is a universal constant, $\frac 1{\sqrt{d}}$
+1{2 \cdot 1.7}$ is a universal constant, $\frac 1{\sqrt{d}}$
 is the factor that accounts for the difference between cell diameter
 and grid point separation,
 $\frac 2d$ accounts for the increase in $\beta$ with space dimension,
