TABLE 1.

Spatial precision in degrees of visual angle by recording condition and filtering level (unfiltered vs. filtered)

Recording condition	Unfiltered data	Filtered data
Stationary pupil (power off)	0.008	0.005
Stationary pupil (power on)	0.020	0.011
Reading task	0.033	0.022
Pursuit task	0.037	0.025

The values in the table were obtained by computing the average standard deviation of horizontal gaze position in each condition.
