A scale for noncentral return matrices
The scale is the maximum of the diagonal difference and a homogeneous off-diagonal size. The latter uses the square root of the quadratic coefficient and a finite sum of the other linear coefficients. This equivalent choice of norm gives exactly the two scaling regimes used in EKL (2006), Lemma 4.6.
