The labels in fn789::usr$root:[e789.multi]surv3752.dat match Martin's list from his inspection of the wiring in the counting house. With these assignments the efficiency of some of the h+h- 900A D trigger components are as follows (from analysis of prescale events): component eff ----------- --- nx1nx3bar 92% susd 84% muup.mudn 95% hhigh 57% ------------ --- overall h+h- 42% (these, by the way, yield a D->KPi xsection of 21 ub/nucleon) For these (and most runs) the TFI was 2/4M + 4/4muLR +4/4LR so the actual efficiency of the hodoscopes and matrix cannot be obtained. We may be able to estimate these using the monte carlo and hodoscope efficiencies measured in earlier runs. I will also look at some of the very early 1000 amp runs where a 3/4LR TFI was used.
