Components of the 3D position, in spatial frame coordinates, of the stylus tip () for one representative trial.
The ‘ * ’ marking the minima correspond to the positions furthest away from the target. The thick solid lines are the data of interest, within 5 seconds before and after the midpoint between two minima.
