(17) Plotting the mean and standard error of the means of these seven sets of data produced a smoothing out of the horopter locus.
(18) Since the two eyes' zero meridians define physiologically the positions of corresponding retinal points, this out-torsion results in a vertical horopter in the mid-sagittal plane which is tilted away from the alert, unparalyzed cat.
(19) Such low-frequency, inter-fixational variation in torsional difference between the eyes must produce spurious horizontal disparities in the upper and lower visual fields, and should thereby limit the precision with which the vertical horopter can be evaluated.
(20) The results produced a refined horopter locus and suggested that the so-called Vieth-Mueller circle is an adequate describer of the empirical longitudinal horopter, except in those cases involving uncorrected aniseikonia.
Image
Definition:
(n.) An imitation, representation, or similitude of any person, thing, or act, sculptured, drawn, painted, or otherwise made perceptible to the sight; a visible presentation; a copy; a likeness; an effigy; a picture; a semblance.

(v. t.) To represent or form an image of; as, the still lake imaged the shore; the mirror imaged her figure.
