A similar number of randomly chosen images were taken for comparison.

Worse statistics due to the very high stream velocity required for stable flow under the conditions of the experiment.

§

Differences in indexing rates are related to sample preparation. A too-high crystal concentration in the sample resulted in many multiple lattices containing diffraction images in the data set (as manifested by a very high hit rate). These were not always indexed by nXDS, thus giving a low indexing rate.
