Neutral Trigger Efficiencies
PBG1
(Looks for back to back energy deposits in the CCAL):
ETOThi
(Looks for 80% of available energy deposited in the CCAL):
Comments:
PBG1 calculations are complete. Note that no efficiencies are calculated for
stacks 1 and 2 since there was no ETOTlo or minbias trigger.
Also excluded due to lack of good data were runs 2034-2037 and 3276.
Due to a timing problem for the super ring 4 neutral mlu, runs 1371-2108
suffered a decreased efficiency.
For runs 688-784 the ETOTlo prescale was 1000.
For runs 801-2092 the prescale was changed to 500.
After run 2094 the prescale was 100 (thus the large increase in number of
events.
For technical reasons, runs 3323-3333 are summarized in the ddbar data
tables.
