hi,
if you want to use the real pattern recognition for the STT, you can use for instance
$VMCWORKDIR/macro/stt/runreco.C
with the following modification.
Instead of the line
PndSttTrackFinderIdeal* sttTrackFinder = new PndSttTrackFinderIdeal(iVerbose);
replace it with
PndSttTrackFinderReal* sttTrackFinder = new PndSttTrackFinderReal(iVerbose);
If you do that, you re going to have at your disposal for further analysis tasks and for each event a TClones array of PndTrackCand each cointaining :
- initial Px of the candidate track at the origin (0,0,0)
- initial Py "
- initial Pz "
- Charge/Total Momentum of the track candidate
- the ORDERED list of hit NUMBERS belonging to the candidate track. Here ordered means from the hit nearest to the vertex to the further away along the Helix trajectory
Cheers Gianluigi
