Note: Whatever is highlighted above in red indicates the status of the data analysis results for this run. Experts are expected to update this page and highlight the right status.
Muon peaks seen by David Paneque indicate that the calibration is roughly correct, yet there is a an overall 10% discrepancy from expect valuesthe expected values. The discrepancy in the individual layers could go up to 15-20%. See presentation in VRVS meeting
David stressed that the analysis is very rough, and that a more detailed analyis is required to evaluate precisely the calilbration
constants.
His selection cuts are
- a:
- da
very simple:
- 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.
Philippe Bruel Philippe argues that the muon peaks are not correct and uses the this root macro.
