Equations (13)–(18) in the paper by Touaa & Sekkal [(2012[Touaa, Z. & Sekkal, N. (2012). Acta Cryst. B68, 378-388.]), Acta Cryst. B68, 378–388 ] are corrected.

In the text (§2) there was a factor of ½ missing from all the last terms in each of equations (13)–(18). The corrected equations are given below.

[{\bf M} \equiv {\bf L}_1 \equiv {\bi B} = {2\pi \over {a_{(111){\rm SL}}}}\left({\sqrt 2} {\bi i}\kern1pt^0 - {{\sqrt 2 } \over 2}{\bi k}^0 \right)\eqno(13)]

[{\bf M} \equiv {\bf L}_2 \equiv {\bi A} = {2\pi \over {a_{(111){\rm SL}}}}\left({ - \sqrt 2} {\bi i}\kern1pt^0 - {{\sqrt 2 } \over 2}{\bi k}^0 \right)\eqno(14)]

[{\bf L} \equiv {\bf L}_3 \equiv {\bi C} = {2\pi \over {a_{(111){\rm SL}}}}\left(-{ {\sqrt 2 } \over 2{L^2}}\kern1pt{\bi j}\kern1pt^0 + {{\sqrt 2 } \over {4L}}{\bi k}^0 \right)\eqno(15)]

[\eqalignno{{\bf X} &\equiv {\bf X}_1 \equiv {\bi B} + {\bi C}\cr & = {2\pi \over {a_{(111){\rm SL}}}}\left\{ {\sqrt 2} {\bi i}\kern1pt^0 - {{\sqrt 2 } \over 2{L^2}}\kern1pt{\bi j}\kern1pt^0 + {1 \over 2}\left( - {\sqrt 2} + {{\sqrt 2 } \over 2L} \kern1.5pt\right){\bi k}^0 \right\}\cr & & (16)}]

[\eqalignno{{\bf X} \equiv &\, {\bf X}_2 \equiv {\bi A} + {\bi C}\cr =\, & {2\pi \over {a_{(111){\rm SL}}}}\bigg\{ { - \sqrt 2} {\bi i}\kern1pt^0 - {{\sqrt 2 } \over 2{L^2}}\kern1pt{\bi j}\kern1pt^0 + {1 \over 2}\bigg( - {\sqrt 2} + {{\sqrt 2 } \over 2L} \bigg){\bi k}^0 \bigg\}\cr & &(17)}]

[{\bf Z} \equiv {\bf X}_3 \equiv {\bi A} + {\bi B} = {2\pi \over {a_{(111){\rm SL}}}}\left({ - \sqrt 2 {\bi k}^0} \right) \eqno(18)]

This typesetting mistake occurred only in the text. The correct equations (including the factor of ½) were used in the calculations in §3 of the paper, so the results and the conclusions were not affected by this omission.
