- FDC
- Lubomir checked FDC using cosmics and filled the spreadsheet where we compare the problematic channels year-by-year. In short - there are no new problematic channels, most of them were present in the last year check, several were not but were intermittent in the past years.
- There was some noise in FDC2 Cell1 in run 80135 (8/24 evening) identified as sparking close to the last wire, that stopped now. Will keep an eye on it.

- Tracking
- Alex showed pion and proton pull distribution for different soft version and FDC tilts. After long discussions there have been some new ideas: try to lock FDC and CDC together when do the tilt; use low energy data where we expect more tracks crossing both detectors, also rotate the magnetic field together with the FDC.
