The authors regret the following unintentional omission of citations which have described earlier the potential for variable-period undulators (Shenoy et al., 2003), and would like to thank Dr Roman Tatchyn for bringing this to our attention: Tatchyn, R. (1989). Nucl. Instrum. Methods Phys. Res. A, 275, 430–434; Tatchyn, R. & Cremer, T. (1990). IEEE Trans. Magn. 26, 3102–3123.
