I'm not an expert of the calibration, so can someone comment on that ?
More muon peaks:
David had another quick look to the runs proposed by Johan in an e-mail sent to the beamlist on July 18, 2006.
Those are runs 700000276 to 700000286 and runs 700000490 to 700000500.
For simplicity (and to be quick) he used the same cuts he used before. That is:
- TkrNumTracks == 1
- Tkr1Hits > 20
- TMath::Abs((acos(Tkr1ZDir)*(180./3.14159))-180.) < 20
- GltTower == 2 (3) ; This is used to select rougly events hiting the calorimeter of the 2 (3) tower.
Somehow, in ALL those runs the location of the muon peaks is wrong by more than a factor 2.
Below plots are provided for run 280 and 495. All runs are very similar.
