Subjective alignments of the stimulus at different pupil positions for three subjects: A) 20093, B) 20106, and C) 10003. Pupil offsets are relative to the reference pupil position at zero. Subjects’ alignments are expressed as ΔTCA, the change in TCA offset (λ = 532 and 840 nm) relative to its magnitude at the reference pupil position. Data were fit with ordinary least squares (OLS) regression separately for horizontal (blue rightward triangles) and vertical (gray upward triangles) changes in TCA for horizontal and vertical pupil offsets, respectively.
