Equations (13)-(18) in the paper by Touaa & Sekkal [(2012), 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.
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.
