An equation in the paper by Weitkamp et al. [(2011), J. Synchrotron Rad. 18, 617-629] is corrected.

There was a mistake in equation (6) in the paper by Weitkamp et al. (2011)[Weitkamp, T., Haas, D., Wegrzynek, D. & Rack, A. (2011). J. Synchrotron Rad. 18, 617-629.]. The equation should read

[\varphi(x,y)={{\delta}\over{2\beta}}\,\,\ln\left({\cal F}^{-1}\left\{{{{\cal F}\left[I(x,y)/I_{0}(x,y)\right]} \over {1+[\lambda z\delta/(4\pi\beta)]\,(u^{2}+v^{2})}}\right\}\right).\eqno(6)]
