(a) 2D correlation coefficient of the revolving experimental far field from Fig. 4(a) and the reference far field. The sinusoidal fit (red) determines the far field rotation (FF rot.). (b) Experimental and theoretical far field rotation versus δ. A linear dependency with an inverse slope of (67 ± 5)nm/° for the experimental and (62 ± 4)nm/° for the theoretical data is found.
