Fig. 1. Frequency of diffraction patterns as a function of the relative change in crystal orientation.

The change in crystal orientation was characterized by the reciprocal space vector $\stackrel{\rightharpoonup }{a}$, between consecutive diffraction measurements (separated in time by 886 ns) within the X-ray pulse train. The liquid jet speed was 42 m/s. An increase in frequency above 0.04 for consecutive images with a change in orientation of less than 5 degrees, indicated by the region shaded in red, can be observed and were classified as double hit crystals.
