Move some part from the DHadronic.muse to here:

Fit MC samples

Look at biases on the extracted mass with respect to the truth - and across modes.

Signal MC

   $c3python myyields.py  signal --single

Selected event plots:

signal_Single_D0B_to_Kpi

signal_Single_D0_to_Kpi.evt
signal_Single_D0B_to_Kpi.evt

Combine the D0 and D0B together

signal_Single_D0_D0B_to_Kpi.evt

  $cd Roofit
  $. setup.sh
  $c3python single_tag_fit.py --mode 0 --file \
  signal_Single_D0_D0B_to_Kpi.evt mc

After done the same thing for the D+ and D-, one get:

single_Single_D0AndD0B_to_Kpi.eps

single_Single_DpAndDm_to_Kpipi.eps

Generic MC

generic_Single_D0AndD0B_to_Kpi

generic_Single_DpAndDm_to_Kpipi

Fit Data

Compare the mass difference you find to the assumptions made in the beam energy correction determination. Is there an inconsistency? If so what are the implications?

data_Single_D0AndD0B_to_Kpi

data_Single_DpAndDm_to_Kpipi

New Script DHad.py

D0_to_Kpi Signal MC

c3python DHad.py -t s -m 0 --tag s --sign 1
