Fig. 4: Integrated patterns from summed images and histograms showing the results of the spot finding approach.

Data are shown for (a) run 505, and for (b) all runs collected from the Ag coupler in DAC 8 where SI was observed. The construction of the histogram for run 505 is illustrated in Supplementary Movie 1. When the Re contribution (estimated from the first pulse pattern) is subtracted from integrated patterns, they are in good agreement with the histogram. Source data are provided as a Source Data file.
