    • We observe the sample under an angle of (Formula presented) with respect to the symmetry axis of our trap. (The data are corrected for this effect.) This limits the observation of phase stripes at long expansion times. Using a positive 1951 USAF resolution target, the optical resolution was measured to be (Formula presented) ((Formula presented) half-width; note that black squares in Fig.� 2 also represent half-widths). Therefore any broadening due to the optics can be neglected
