Extended Data Fig. 8: Comparing modes from light and dark data.

a, The first five chronos obtained from light data ordered according to pump-probe delay. b, The first five chronos obtained from dark data lexicographically sorted according to run numbers followed by event numbers. The first two chronos are identical, except for scale. This is a hallmark of a one-parameter process. Correlation analysis shows the single-parameter process correlates with the integrated Bragg spot intensity (Pearson correlation: 0.93), most likely pertaining to drift in the incident beam intensity. The subsequent chronos represent noise.
