Track stitching in PMA
0%
Description
While studying some 35t events, I noticed something strange in the stitching algorithm in PMA.
Here is a reconstructed 35t data event if we turn off stitching between TPCs:
This is the same event after we turn on stitching between TPCs:
For the stitched track (id=1), I printed out the trajectory point index, x, y, z, dirx, diry, dirz. Near the track end:

The last few points are identical and the directions are also wrong.
The unstitched track does not have this problem:

Also in the function
void pma::ProjectionMatchingAlg::mergeTracks(pma::Track3D& dst, pma::Track3D& src, bool reopt) const
if I turn off optimization (reopt=false), the problem seems to go away. So the problem seems to be related to the optimization of merged track.
Leigh, since you worked on the cathode crossing stitcher, do you have any comments? Thanks.

Just to confirm, is this just stitching between TPCs with the same drift direction or across the APA? It should probably happen in both cases since the underlying functions called by PMA to stitch the tracks are the same.
I believe that Christoph Alt has seen something similar in the dual phase (which doesn't need CPA / APA stitching), so I hope he can chip in with a description of what he saw and what he has managed to discover about it so far. I imagine this could therefore be an issue with the code in pma::Track3D::optimize or the deeper versions that update pma::Node3D or pma::Hit3D objects.

Do you have the full log of trajectory points for the two unstitched tracks? It'd be good to make sure that the number of trajectory points in the stitched track is consistent with the number from the two unstitched tracks.
