Notes. The tilt angle θ between the NSC and the GP is a free parameter in the fits.

^(a)

Fits to the symmetrized images that we create by assuming symmetry of the NSC with respect to a rotated axis with the GP. The value of the tilt angles are the mean of the values obtained in the fits for the images applying two different masks.

^(b)

The tilt angle between the NSC and the GP in degrees. Positive angles are clockwise with respect to the GP.
