Shift of TRD digi time distribution: TB vs EbE
I discovered that TRD digi time distribution is shifted left by ~55 ns in time-based simulation compared to the event-by-event mode (see attached).
Is it an expected feature? Which value is the right one?
The two distributions were produced using the same transport file, sis100_electron setup, CbmRoot 15c78e78, FairRoot 18.2.1, FairSoft jun19p2.
As far as I understand this should not affect the performance in the EbE case but the proper value is needed for tuning the time-based reconstruction.
