## Agenda¶

Rogers and Victoria:- "Top-down" list of plots

- The low-level track reconstruction (everything up to pattern recognition) should be written up ASAP. I think it is at a reasonable point?

- 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

- What is the impurity reported by MC, based on Scott cuts?
- Can we confirm that the muon shoulder arises due to diffuser? i.e. extrapolate reconstructed tracks back to the diffuser position, what is the radius?

- Any results for likelihood-based PID?

- What is the source of disagreement between TOF and tracker?
- Rogers - error_propagation.pdf
- What is the material budget between TOF and tracker? Is it correct? (See Francois also)

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

- Is the diffuser fixed yet? What about upstream tracker window?
- Can the agreement between MC and data be improved?
- 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)?

- Emittance calculation etc - any updates?
