The positions of the stable eigenvectors and the limb trajectory change with drive strength. (A) Small drive leads to small Mn - F output and stable eigenvectors that lie in a region of small positive velocity, but the limb trajectory enters this phase far below them. (B) Large drive, with large Mn - F output, yields stable eigenvectors shifted farther upward than in (A), such that trajectories with larger initial fStance velocities still lie below them. Time points on the limb trajectory are shown with stars, while the color-coordinated lines are the corresponding stable eigenvectors.
