Errors in the article by Smilgies [J. Appl. Cryst. (2019), 52, 247–251] are corrected.
Keywords: soft materials; lamellae; grazing incidence scattering; area detectors.
The equations given by Smilgies (2019![[Smilgies, D.-M. (2019). J. Appl. Cryst. 52, 247-251.]](../../../../../../logos/arrows/j_arr.gif "Smilgies, D.-M. (2019). J. Appl. Cryst. 52, 247-251.")
) contain two errors:
Equation (5) should read
![[2\theta = \arctan\left [{\left({{x^2} + {z^2}} \right)/L} \right].]](teximages/vh5141fd1.svg)
Equation (11) should read
![[{q_y} = {{2\pi } \over \lambda }\sin \left({{\psi}} \right)\cos({{\beta}}).]](teximages/vh5141fd2.svg)
Note also that the d spacing used for generating the images in Fig. 4 is 1.5 nm. The notations qhkl and Ghkl are used interchangeably for the scattering vector associated with Bragg reflection hkl.
