This method performs a regression of the structure function against

[math]\displaystyle{ D = a_0 + a_1 (\delta r_0)^{2/3}+a_3((\delta r_0)^{2/3})^3 }[/math]

The last term includes the influence of non-turbulent motions which result in a velocity difference between bins which varies linearly with separation distance and hence contributes to [math]\displaystyle{ D(n,\delta) }[/math] as [math]\displaystyle{ (\delta r_0)^2 }[/math]
