sPHENIX tracking discussion

Hi Christof,

Cool! If you produce evaluation files, I can make the resolution plots pretty easily. Are you using the SvtxEvaluator or Hugo's evaluator?

Subject: [EXTERNAL] [Sphenix-tracking-l] Tracking efficiency with parameterized errors

 

Hi Everybody, 

I ran a few jobs resetting the errors in the TrkrClusters from the values assiged by the clusterizer to either fixed rphi errors or errors derived from a parametrization based on the track angles.

Below is a plot of the tracking efficiency using default errors, fixed errors and parmetrized errors. The efficiencies are identical.

Note of caution, I reset the errors in the PHTpcTrackSeedCircleFit module, so this happens after the cluster cleaner is run. 

I will rerun a version now setting the cluster error to a fixed value in the clusterizer already. This will then bypass the ClusterCleaner. 

@Joe I think it would be worthwhile to check the momentum resolution with the parameterized errors. 

What machinery do you use to produce your plots? It will take a while untill I can commit my stuff to github. Can I produce some 

output files you can use process to plot the resolution?

Cheers
