Two-dimensional GISANS data measured simultaneously in a TOF-GISANS experiment. From top left to bottom right, the corresponding mean wavelengths are 0.25, 0.28, 0.30, 0.33, 0.37, 0.40, 0.44, 0.48, 0.53, 0.58, 0.64, 0.71, 0.77, 0.85, 0.93, 1.02, 1.12 and 1.23 nm. The intensities are shown on a logarithmic scale, as indicated by the color bar. Each image covers a different range in (qy, qz) space, as explained in the text. In the top left two-dimensional image the sample horizon (dashed line), the specular peak (S), the Yoneda peak (Y) and the direct beam position (D) are indicated. Adapted from Müller-Buschbaum et al.
