Check out (cvs co) or copy (cp -r) subsystems TrackerReco/PixelTrackFinder, TrackerReco/PixelTrackFit and TrackerReco/TkHitTriplets. The relevant changes are in this tgz file  . Overwrite and add new files by tar -xvzf TrackerReco.tgz.
Compile with eval `scramv1 runtime -csh`; scramv1 build. A new subsystem TrackerReco/LowPt was created, go to TrackerReco/LowPt/test.
The file orcarc.aa contains parameters. The tunable ones are:
LowPt:ptMin = 0.175
LowPt:originRadius = 0.1
LowPt:originHalfLength = 0.1
Enter proper InputCollections and InputFileCatalogURL values. Start reconstruction by TestLowPt -c orcarc.aa.
A sample area with data files is set up on AFS below ~sikler/public/ORCA_8_13_0. |
