## Agenda¶

Durga:- Estimate of the systematic error associated with rate-dependence in TOF?
- Does TOF calibration vs path length help at all?

- What dos the p-value distribution look like? Are the p-values not uniform if not, why not?
- What is the error on tracker recon introduced by the field non-uniformity?
- What is the error on tracker recon introduced by the disagreement between model and field maps cf: slide 3 of

https://indico.cern.ch/event/485764/contribution/2005672/attachments/1249829/1842249/fieldmapping.pdf

- Discussion of muon shoulder; radial cuts; etc

- Any results for likelihood-based PID?

- What is the source of disagreement between TOF and tracker?
- What is the material budget between TOF and tracker? Is it correct? (See Francois also)
- What is the solenoid alignment like

- Are the OPERA model and Hall probes consistent? How big are the inconsistencies?
- Continue trying to untangle the field mapping data for SSU

- Can the agreement between MC and data be improved? Dipole fiddling?
- At what statistical significance do MC and data disagree?
- What are the systematic errors (e.g. from quad/dipole/solenoid settings, incorrect material model etc)?

- Decoupled/2D emittance calculation?

- Issue with MC
- Rayner calibration was not working with MC; taking calibrations from data and plugging them into MC was not okay
- Got good results by doing calibration using TOF0
- Fit fails on TOF1

- Offset of 60-100 ps - no progress
- Speed of light offset did not give the expected correction; needs digging
