Corrected methods details should guide reanalysis of Park-Holohan et al. (2012); leaves open whether original conclusions require revision.
In the article by Park-Holohan et al. (2012) there was an error in the Methods section entitled ‘X-ray diffraction experiments’ on page 1975. Sentences 9–11 of this section should read as follows: X-ray diffraction patterns were recorded using a high sensitivity fibre-optically coupled CCD detector (FReLoN) with an active area 100 × 100 mm2 (Sztucki et al. 2010) and the detector was mounted in an evacuated flight tube 2.3 m from the fibre bundle. The 2048 × 2048 pixels of the CCD were binned by 8 in the horizontal direction and 2 in the vertical direction before the readout to increase signal-to-noise ratio. The point spread function of the FReLoN detector was ∼80 μm (FWHM), and the combined instrumental point spread function was negligible compared with the radial width of the M3 reflection.
