All,
As discussed during today's tracking meeting,
The 'fallback' drift velocity that I have used to process run 53285
G4TPC::tpc_drift_velocity_reco = 0.00726182; // from run 50015
whereas the default fallback value is 0.007 (from
Common/Trkr_TpcReadoutInit.C)
I got this updated value from what's in the database, and using it, although
not perfect, does improve the matching to the Silicons and to TPOT.

If people agree, I'd like to update the fallback value in the official macro.
This until we have an automatic way of getting the drift velocity on a per
runnumber basis.

Hugo
