keyword=Coincidence Time BumpsWe made a check of the funny bumps in TC spectra, see fig. 1
Top-left: full spectrum. Top-right: require event type 5, it cleans
up most of the funny bumps. Bottom-left: For event type 1 (R-arm
trigger) we get an overflow peak at 12 bits. Bottom-right: For event
type 3 (L-arm trigger) we get a self-timing peak at around 50 nsec.
Some self-timing and overflows appear in event type 5 also.
Note the cut tce>0. This is because in 5.8% of physics triggers, this
analyzer sees no TC data (no data in TDC ?!). Don't know why yet.
