Parameters calculated for each VGS

Saccadic parameter	Definition	Unit
Latency	The time interval between the appearance of the eccentric dot and the start of the VGS	ms
Duration	The time interval difference between the start and the end of VGS	ms
Amplitude	The difference in degrees of visual angle between gaze location at the start and the end of the VGS	°
Mean velocity	The average velocity of the VGS	°/ms
Peak velocity	Maximum velocity of the VGS	°/ms
Gain	The ratio between amplitude saccade/amplitude target
