Sensitivity of tracking delay and residual error. A, Residual tracking error, after removing the tracking delay, as a function of the number of receptive fields covering each position in space. B, Residual tracking error as a function of target size and speed, for a coverage factor of ∼2. All plots are from trial-averaged experimental data. Colored shaded regions are the ±1 SD error contours from single-trial data. C, Tracking delay as a function of the number of receptive fields covering each position in space. Gray bars (A, C) show the coverage factor used for most analyses.
