Below are some performance plots of the eTOF produced with the fast offline data from runs 20066013 and 20066020. I only applied manually some position offsets corrections and a vary crude T0 offset correction. No slewing corrections so far.
The time of flight is obtained from the eTOF hit stop time and the start time from the bTOF header.
Many things can (and should ;) ) still be optimized.
