|Type||Single pair||Double pair||Single w/had||Double w/had|
Looked at another way, if I require two pair in the trigger I get reduction rates as follows:
|Type||w/o had||w/ had trigger|
"Rear either" is an alternative trigger requiring either rear BSU or rear TSU, "rear both" is the standard requiring both scintillators to fire.
Remember that this particular trigger cuts the Z sample in half, so reduction ratios of 2.5 are not very helpful in reducing the background.
