Elog, CDB, and Reconstruction¶
Elog entries are ok.
CDB uploaded ok.
Online reconstruction is ok.
Note the TOF1 reconstruction from run 9834:
Run 9834 input beam setting is 10-140 (task H28c in https://micewww.pp.rl.ac.uk/projects/operations/wiki/RunPlan20171002)
This was not observed in the other 3-140 or 6-140 settings. D. Rajaram is re-starting on-rec to see if it fixes it. The pattern we observe in the above TOF1 spacepoint is not observed in TOF1 raw PMT plot (TofReduce_tof_pm0pln1.png).
Update: re-starting on-rec fixed the problem:
