Hi Sebastian,
the x-axis joins the hit to the pca, actually it goes from the hit to the pca.
I changed this because I saw that in the Propagate(CbmTrackParP *TStart, CbmTrackParP *TEnd, Int_t PDG) you added the "support for poca with points", i.e.:
if(fPCA==1){// point
TVector3 mom(TStart->GetPx(),TStart->GetPy(),TStart->GetPz());
wiredirection=mom.Cross(fromwiretoextr);
}
so I thought you wanted to make your plane perpendicular to the track direction, is this correct?
Previously the vwi was set to (0,0,0) in the case of pca = 1 and so the fromwiretoextr axis (x-axis of the plane) was from (0,0,0) to the pca...
I hope this is ok...
Ciao,
Lia.
