sPHENIX tracking discussion

[Hugo Pereira Da Costa <hugo.pereira.da.costa AT gmail.com>]

Joe, Christof, others,

1/ the CDB tag I use in the reconstruction macro is the one I got from Tony:


  // condition database
  Enable::CDB = true;
  rc->set_StringFlag("CDB_GLOBALTAG", "ProdA_2024");
  rc->set_uint64Flag("TIMESTAMP", 6);

  // tracking geometry
  std::string geofile = 
CDBInterface::instance()->getUrl("Tracking_Geometry");
  auto ingeo = new Fun4AllRunNodeInputManager("GeoIn");
  ingeo->AddFile(geofile);
  se->registerInputManager(ingeo);

Is this the correct one ?

2/ to Christof: I have updated the slides I posted at 
https://indico.bnl.gov/event/24192/contributions/95299/attachments/56417/96569/TpcResiduals_hp.pdf 
to look in more detail at delta_phi vs layer with charge cut. This is in 
slide 9.

There is a charge dependnece when getting near TPOT, and since each 
charge tends to favor one sector rather than the other, this would point 
to a sector dependent phi misalignment in TPOT, as you hinted during the 
meeting.

3/ Any help about how to add per-layer delta phi (and delta_z) alignment 
offsets via text file would be very appreciated ! (Tony ? Joe ?)

Best,


Hugo
