A printer's error in the paper by Foster, Brown, Nielson & Abrahams [J. Appl. Cryst. (1997). 30, 495–501] is corrected. In §4.2 on p. 497, the displacement Δz(Fe1/Nb1) was given incorrectly as 0.5353 − 0.5063 = 0.1 (7) Å. The correct value for the displacement Δz(Fe1/Nb1) is 0.5353 − 0.5063 = 0.12 (7) Å.
