Ratio of TTF reconstruction errors as a function of noise. In part (a) σ was estimated by finding the minimum of wttf and the plot shows the ratio of TTF error to the minimal error, obtained for true optimal σ. The values are evidently scattered; nevertheless, they remain in a narrow interval. Part (b) illustrates the improvement when the estimated σ is modified by factor 0.35.
