    keyword=scaler bcm asymmetry test

    We used the same signal to test the scaler and HAPPEX bcm asymmetry. For
each DAC setting, we took data from all of 3 arms almost at the same time
to compare. The DAC setting is here:

run number(L/R/Th) DAC value(+/-) DAC asym   
2322 21366 40152   41010 41000    607.86ppm
2323 21367 40153   41100 41000    0.60455%
2324 21368 40154   42000 41000    5.73355%
2325 21369 40155   41001 41000    60.819ppm

Pengjia already posted the test result for HAPPEX daq. The attachment is
the test results from scaler.
