Variance- and covariance trajectories.
Data (solid) and model fits (dashed) of the simplified model without ON noise (fitted parameters: [kA, kPBN, g]; fixed: kON = 0). The top row shows the variance trajectories for the three saccade conditions: control saccades (A), and saccades ipsiversive (B) and contraversive (C) to the side of an inactivated cFN. The bottom row (D/E/F) shows the corresponding covariance trajectories (i.e. the covariance between the eye position at the time shown on the abscissa and the eye position at the end of the saccade). Note the different scaling of the axes for each saccade condition.
