Grazing incidence X-ray diffraction pattern is used as a method for crystalline characterization of thin films. To obtain a qualitative result it is necessary to align the sample correctly. Reasons for an incorrect alignment can be a wrong height setting, a wrong angle of incidence or a not flat lying sample. The aim of this work is to determine the influence and the error of the misalignment to get a good estimation of the quality of the measured diffraction pattern.
