Figure 2
Soliton sample described in §2.1[link]. (Left) Comparison of the reflectivity curves acquired with a point detector (rocking scan) and fully integrated q-space converted XPAD images. Both data sets were corrected for the active (illuminated) area of the sample, and normalized for the same intensity at the total external reflection plateau. (Right) Two-dimensional cuts through the three-dimensional data set (after q-space reconstruction). Note that, in the figure, the horizontal qy axis length is expanded by a factor of 2 with respect to the vertical one (see the length of 0.1 Å−1 scale in the horizontal and vertical directions). Also the qx coordinate was laterally shifted for display purposes. Note the presence of attenuators in the beam when measuring data close to the total external reflection of the beam (arrows). The intensity colour scale is logarithmic and spans over five orders of magnitude, from blue to red.
