Paolo's "system performance talk":https://indico.cern.ch/event/841655/contributions/3582016/attachments/1932648/3201500/Franchini-CM55-System-performance-paper.pdf at "CM55":https://indico.cern.ch/event/841655/ found a tiny number of runs with lower-than-usual track-finding efficiency (96% instead of 98%). <pre>> Do you have the run mumbers for those outliers in the Tracker plot? I can add trawling the eLog to my list of things to do in quiet moments. a couple of outliners in field on downstream tracks 8549 8695 few other in straight tracks 10162 10161 10178 in general between 17/11/2017 and 20/11/2017 there are relatively low efficiencies in straight tracks. Also averaging the helical ones there is a general negative trend, cheers, Paolo</pre> I volunteered to poke Poke around in eLog, etc. and see if there's a possible hardware reason.
