Map of local phase tilts of the wavefront in the focus of the X-ray beam. (a) Relative vertical/horizontal deviations from a planar wavefront with estimated photon intensity coded in colour. The horizontal axis spans 1.3 mrad and the vertical axis spans 1.7 mrad. Each box on the grid has dimensions of 0.1 × 0.1 mrad. (b) Two-dimensional histogram showing the number of events in each box (linear colour scale with black = 0 and white = 75). (c) Map of average photon intensity inside each box coded according to the colour scale on the left.
