keyword=Timing changes in T7
Timing changes at the Hall:
HAND trigger (T7): the width of HAND trigger was changed from 150ns to 180ns. The width of the pulse from LHRS (T3) is 50ns (wasn't changed), and the time difference to the end of HAND trigger is now 50ns. We checked that there is still an output of a coincidence signal between LHRS and HAND.
BigBite: The width of the signal from BB is ~140ns. There is a time difference of ~15ns between the edges of the LHRS and BB signals. We couldn't change the width of the BB signal without touching other timing features, such as T5 or Retiming etc.
