SAD phasing by combination of direct methods with the Solve/Resolve procedure

In the paper by Wang et al. (2004) an error in equation (18) was published. The correct version of this equation is given below.\eqalignno {P{_+} (\Delta \varphi _{\bf h}) = &\textstyle {1 \over 2} + {1 \over 2} \tanh \biggr\{\sin |\Delta \varphi _{\bf h}|\biggr [\sum\limits_{{\bf h}'} m_{\bf h'} m_{{\bf h} - {\bf h}'}\cr\quad &{\times} \,\kappa \sin (\Phi '_3 + \Delta \varphi _{{\bf h'}\,{\rm best}} + \Delta \varphi _{{\bf h} - {\bf h}'\,{\rm best}}) + x\sin \delta _{\bf h}\biggr] \biggr\} & (18)}.The following acknowledgement was also missing from the paper.
