    • The correlation length (〈) has been calculated by fitting the peak with a Lorentzian distribution function and using the Scherrer equation as reported in ref 51: 〈 = 0.89 λ/(ω cos θ), wherein λ is the wavelength of the X-rays, ω is the full width at half-maximum of the peak in radians, and θ is Bragg angle of the maximum of the peak

    • Two-dimensional X-ray scattering measurements on shear aligned samples showed that all small angle diffraction peaks split up in two opposing maxima that align in the same direction on the two-dimensional detector. Furthermore, the wide angle maximum related to the stacking of A-BTA splits up in two maxima perpendicular to the small angle diffraction peaks. These measurements confirm that all observed small angle diffraction peaks observed in the LC phase arise from order in a single plane perpendicular to the stacking direction of the A-BTA discotics.
