  50 datasets were generated with 6099 events per data set using 0.68 b2pipi (sf1=1 and ssb = 0.68) and 0.32 combinatoric background (MassDistribution) mass distribution. The asymmetry fitter was used to fit for Bd asymmetries only with sf1'=0.68 and obtained the following:
Adir Bd - input was 0.38 and fitted was 0.3953 ± 0.0476 ( AdirBd)
Amix Bd - input was 0.61 and fitted was 0.6503 ± 0.0311 ( AmixBd)
Then re-ran same job with 150 data sets with 2000 events per data set and fitted for the following:
Adir Bd - input was 0.38 and fitted was 0.4338 ± 0.0196 ( AdirBd)
Amix Bd - input was 0.61 and fitted was 0.6619 ± 0.0197 ( AmixBd)
The asymmetry plot is shown here .
