sPHENIX discussion of software

[Christof E Roland <cer AT mit.edu>]

Hi Everybody,

just a quick followup on the discussions in the simulation meeting. 

- the genfit based tracking does not suffer from the event by event mvtx half shell problem Tony reported for the ACTS tracking. The matching inefficiency for the MVTX part is randomly distributed event by event in phi.

- Setting the phi and z errors of clusters with high total ADC value (>500) to the clusterwidth/sqrt(12) gives a significant improvement for the MTVX matching efficiency. See attached plot below. Green is cluster errors as usual. Black dots if modified cluster errors in GenFitTrkProp.

Looks like this is worth pursueing further. 

Cheers

   Christof
