Simulations of eye movements in a gondola centrifuge as compared with the pattern of data, for the two different versions of the model: Filter Model and GIF-Resolution Model. The actual pattern of data (x's) is as shown in McGrath et al. [31]. Details of the models’ parameter values are given in the text. For the Filter Model, the two different values of τl gave graphs that were barely distinguishable, so the value τl = 0.25 s is used for this display. (A) Centrifuge acceleration, horizontal slow phase velocity (SPV) of eye movements. (B) Centrifuge acceleration, vertical SPV. (C) Centrifuge deceleration, horizontal SPV. (D) Centrifuge deceleration, vertical SPV.
