Description

Paolo's system performance talk at CM55 found a tiny number of runs with lower-than-usual track-finding efficiency (96% instead of 98%).

> 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

I volunteered to poke around in eLog, etc. and see if there's a possible hardware reason.
