![]() This task may be combined with distortion correction to produce intensity information and error estimates. For powder diffraction experiments the additional task of converting a two-dimensional image to a one-dimensional spectrum is used to allow Rietveld analysis. It is better to account for the distortions within scientific analysis software, but often it is more practical to correct the distortions to produce ‘idealised’ data.Ĭalibration methods and software have been developed for single crystal diffraction experiments, using both approaches. Intensity non-linearity, spatial distortion, and non-uniformity of intensity response, are the primary considerations. To obtain accurate angle and intensity information, it is necessary to calibrate, and apply corrections. Detector systems introduce distortions into acquired data.
