Residual∆b-values reflecting |b^exact(including all imaging gradients) – b^PGSE (eq.1b)|, for the five diffusion experiments described in Fig. 2. The columns correspond one-to-one to these sequences lettering, and the rows correspond to diffusion gradients applied along the indicated axes. Notice the minimal disturbance evidenced by the sequences in Fig. 2D, 2E. Parameters assumed for these diffusion calculations are δ= 3ms, ∆ = 14ms (except for Fig. 4D where ∆ = 11.4ms). The gradient and timing values taken into account for the b-value calculation are according to the experimental scanning parameters presented in Fig. 3 and Fig. B1 of Appendix B
