GISAXS measurements (upper row) versus theoretical expectation (lower row) of surrounded field 1 at different rotation angles φ. At φ = −10° (left) the X-ray beam is oriented along the surrounding structure, showing the scattering orders of the surroundings and a rich diffuse background. At φ = −5° (middle) the X-ray beam is equally misaligned to the surroundings and the grating target, with only the first diffraction order visible at [\alpha_{\rm{f}}] ≃ 1.2° for the surroundings and the target, respectively. With the X-ray beam aligned to the target (φ = 0°, right), only the scattering of the target is visible on the detector. An animated sequence showing scattering patterns from φ = −10° to φ = 0° in steps of [\Delta\varphi] = 0.1° is available in the supporting information.
