Table D-I. Ratio of MDX_fitted and MDX_true, SNR=20.

MDX_fitted is the average of 800 MDX's obtained from fitted maximum values of noisy derivatives and MDX_true is the MDX of the noiseless data. The standard deviation σ of the ratio between the fitted value of MDX and the true value of MDX gets larger at lower flow.
