Summary
The jitter of L0 board is less than 2.4*100ps, see "YELLOW_CC","(TrigL0Latch&0x40)"
CP fires only in 1905 out of 7507 events. Need to be delayed from 428 to 500 = 7 ns
If the reading in TDC8 is less than 500 then the signal could be missed!
CN_CP = 352 need to be delayed 15 ns.
VME_T0P is missing in the scalers.
