Figure 3.

Diffracted intensity, corrected for polarization, effective area, and Lorentz factor, versus the in-plane component Q_xy of the scattering vector measured at 20 mN/m for the ATFLL mixture. The measured intensity is integrated over a Q_z range from 0 to 0.4 Å⁻¹. The horizontal resolution of 0.008 Å⁻¹ was determined by a Soller collimator mounted in front of the PSD. A Lorentzian model peak was least-square-fitted to the measured intensities of the Bragg peak. (Inset) Broader Q_xy range to show the additional broad halo.
