(a) Presentation of the three-dimensional dataset I(z = αf, y = φ, E) recorded with the pnCCD in on-axis setting. For better visualization the measured intensity distribution is projected perpendicularly onto each of the three visible interfaces of the `data-volume' limited by −0.52° < αf < 0.58° in the z-axis, −0.48° < φ < 0.62° in the x-axis, and 6 keV < E < 35 keV. In addition, two slices of constant energy E1 = 20 keV and E2 = 23 keV are shown as insets providing similar information as a GISAXS experiment at this selected energy. (b) The data volume shown in (a) after transformation into reciprocal space I(qx, qy, qz). The data volume is limited by −0.0015 < qx < 0.0015, −0.12 < qy < 0.12, 0.0 < qz < 0.5 (all values in Å−1). Insets: slices for constant qz at the second- and third-order Bragg peak qz = 0.23 Å−1 and qz = 0.34 Å−1 (logarithmic colour scale).
