Thus, asymptotically: (a )THEORY σ → 0: = a 0 + O (σ ) = 2 h0 + O (σ ε Lx ) (54) Table 2.

We conclude that the theoretical prediction of σΦ given by equation (52) with a ≈ a0 is robust. Finally - after some manipulations involving statistics from the Z-Φ transform (Eqs.(45),(46)) and the spectral solution for σΦ - one obtains, to first order: (a): σZSALT (x) ≈ c σlnK λlnK a or (b): σ ZSALT (x) ≈ c σ ln K λln K...
