Figure 3
(a) Changes in the details of a diffraction spot with dose. The blue box corresponds to a pixel on the PILATUS detector at 300 mm distance and is retained in the same position to illustrate the shift in the centre of the diffraction spot with exposure. The dose figures correspond to the estimates for the start and end of each 20 s exposure. (b) Vertical profiles of diffraction spots shown in (a). These were summed across 20 horizontal pixels to compensate for the weaker intensities and noisier data at higher dose. In this plot the detector offset has been subtracted.
