Anomalous Run 18 AuAu27 data

 Following up on this post: Big abort gap cleaning charge

A reminder that this is the anomaly seen in run 19132076 that Ben found during his calibration work of sDCA vs time [sec]:




There are plots of DCA vs. event number within the file (not exactly the same as time, but a reasonable proxy) from various runs during the first half of Run 18 AuAu27 data-taking:
