An error in Fig. 2(b) in the paper by Hulbert & Kriven [J. Appl. Cryst. (2023), 56, 160–166] is corrected.
Keywords: Debye–Scherrer; transmission; specimen-to-detector distance; displacement correction equation; powder X-ray diffraction; area detectors.
In the article by Hulbert & Kriven (2023![[Hulbert, B. S. & Kriven, W. M. (2023). J. Appl. Cryst. 56, 160-166.]](../../../../../../logos/arrows/j_arr.gif "Hulbert, B. S. & Kriven, W. M. (2023). J. Appl. Cryst. 56, 160-166."){kind=small}
), there is an error in Fig. 2(b) which shows the Bragg–Brentano geometry for an X-ray diffraction (XRD) experiment. The arc denoting the angle 2θ + δ was mistakenly drawn so that it ended at the base of the specimen. However, it should extend to the incident beam. The revised Fig. 2(b) diagram is given here, shown in Fig. 1. Both the derived equation and the conclusions in the original article are unaffected by this figure correction.
