The identifier provides information on the horses in the study. The ratio between the number of pixels counted in the traced pupil and the number counted in the traced iris is the normalized area 1 at the beginning and the normalized area 2 after a defined time. The most right column shows the relative change in area size. The bottom two rows show the average values and one standard deviation, respectively.
