The pupil of the error between the true and calibrated PSG matrices as a variation of the intensity noise. The colormap displays linear relation between the input normalized intensity noise and the error across the pupil of the element (3,1) of the 4 ×4 PSG error matrix ΔW3,1(β=9).The pupil is scaled to have a radius of 1
