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]:
![](/STAR/system/files/userfiles/17/image/Calibrations/SpaceCharge_GridLeak/Run18_AuAu27/AbortGap/76_cons_4p5e-05_ionV_155.png)
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:
More to come.
