The EC-parameters estimated with a quadratic model for the 1.5 mm ($\mathcal{B}$) was fitted to a second order polynomial of the diffusion gradients (the model given by Eqs. (B3), (B5)). The parameter estimates for the polynomial were used to predict what the EC-parameters should be for the 2 mm data ($\mathcal{A}$). The solid black lines are the estimated EC-parameters for the x- (left) and x²-components (right) estimated directly from the 2 mm data and the dashed gray lines are the predictions made from the 1.5 mm data.
