R16b skims Run2 was used.
On Peak data luminosity: 59.4 fb-1

Tihghter Kaon Selection is applied.
D prob > 0.001 and B prob > 0.01 applied
|cosTheta_{Dl-nonDl}| < 0.92 applied

TrkEff PID corrections are applied.


Validation fit

Use ccbar, uds and tautau MC

1. BF re-weighted histograms + new D/D*/D** hadronic decay BF
      new t_+0
      Old BF ratios for D**lnu/DPilnu
