keyword=happex asymmetry test by using local helicity control board

We tested the happex and scaler asymmetry by using DAC signal for several
different asymmetry number, here it is:

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

for each DAC value:
41000:1.25282V
41001:1.2529724V
41010:1.254344V
41100:1.26806V
42000:1.40522V

For happex asymmetry, shown in attachment; for scaler asymmetry, chao
will post it later.
