As Peter reported in the previous summary, in the first part of this shift we investigated the RTOF3 TDC problem.
By swapping top and bottom TDCs (run 6243) the problem went away. After putting everything back (run 6244), the problem was gone! I believe the cable had been bumped at some point... pretty weird.
We also looked into the LTOF9 bottom problem, as it seems low on the scalers.
Moving it to an adjacent channel proved to us the signal was normal. We did not want to take more of the beam time to investigate this - at this point we are sure the TOF signal is OK, there is a problem between the splitter and the scalers.

Unpol D2 runs 6245-6249 taken in the second part of this shift. Crunching.
