keyword=Left HRS Triggers for Scalers and TDC
I disconnected the trigger cable coming from the BigBite weldment to the
left HRS used for the left HRS scalers during Transversity.
I then connected the HRS local copy of T3 to the normalization scalers
and
to the 1875 and 1877 TDC trigger copies. I also sent a copy of the T4
and
T8 triggers to the 1877 in ROC 4, slot 9. I verified that the signals
were
timed properly with respect to the TDC gate. I also put a copy of the
L1A
from left HRS into the 1875 and 1877 TDCs. I kept the mapping almost the
same from Transversity. Here is the TDC map for the decdata class for
the left HRS.

If needed I can add T4 into the left HRS later.
