I am attempting to use the pTrel/d0Sig fit in the single muon bin either as a systematic or as a central result.  I fixed the Drell Yan fraction relative to the W+heavy component using the number obtained from the absolutely normalized sample,  15% for TCE.  The fit looks like this:

The fit output is as follows:

N(h)=1805 +- 50

N(DY)=319

N(l)=1262 +- 59

There is still a large discrepancy with the absolutely normalized result.  The corresponding absolutely normalized pTrel and d0Sig plots are below.

The numbers for this are:

QCD=303

W+b=198

W+c=537

tt=155

Diboson=49

Z+heavy=22

Z->tau tau=100

Drell Yan=36

W+jets=1497

Total background=2897

Total data=3494

Summing the contributions to compare to the fit, we get

N(heavy absolute)=890

N(DY absolute)=158

N(light absolute)=1849

There is twice as much heavy and Drell Yan from the fit and less light.  Also note that the absolute prediction is low by a factor of 20%.
