Errors in the paper by Kanaki, Jackson, Hall-Wilton, Piscitelli, Kirstein & Andersen [J. Appl. Cryst. (2013), 46, 1031-1037 ] are corrected.

In equation (5) of Kanaki et al. (2013[Kanaki, K., Jackson, A., Hall-Wilton, R., Piscitelli, F., Kirstein, O. & Andersen, K. H. (2013). J. Appl. Cryst. 46, 1031-1037.]), a factor of 2 is missing from the wavelength contribution to the Q resolution. The correct equation is

[\delta Q = \left\{ \left[ {{2 \pi \cos (\theta / 2)}\over {\lambda}} \delta \theta \right]^2 + \left[{{4 \pi \sin (\theta/2)}\over{\lambda^2}}\delta \lambda \right]^2 \right\}^{1/2}. \eqno(1)]

Figs. 12 and 13 of Kanaki et al. (2013[Kanaki, K., Jackson, A., Hall-Wilton, R., Piscitelli, F., Kirstein, O. & Andersen, K. H. (2013). J. Appl. Cryst. 46, 1031-1037.]) are updated as Figs. 1[link] and 2[link] of the current article to reflect the correction.

In equation (6) of Kanaki et al. (2013[Kanaki, K., Jackson, A., Hall-Wilton, R., Piscitelli, F., Kirstein, O. & Andersen, K. H. (2013). J. Appl. Cryst. 46, 1031-1037.]), the brackets are missing a square root. The correct version is

[\delta\lambda = 3956\left( {{\delta t^2}\over{L^2}} + {{t^2 \delta L^2}\over{L^4}}\right)^{1/2}. \eqno(2)]
