New DB table for TPC GridLeak variation by sector

The TPC GridLeak distortion is understood to be due ion generated in the high gain region near the TPC anode wires leaking out into the main TPC volume via the gap in ground (cathode) and gated gri

STAR CFEngine policies

 

First stab at a CFEngine policy list and applicability.   The complexity is an initial guess at this point.

 

Effects of TPC SC & GL distortions on vertexing

The TPC SpaceCharge & GridLeak distortions lead to effective rotations of tracks about a radial position somewhere in the middle of the TPC.

A more realistic geometry for PredictSpaceChargeDistortion

The version of StMagUtilities::PredictSpaceChargeDistortion() which we have been using for many years to calibrate SpaceCharge in the TPC has relied on a very simplified version of the TPC geometry
