In previous study, we met the discrepancy between Data and Embedding during the background estimation procedure. One of the possible reason is the mis-matching between track pT and EMC ET.  To investigate the impact from this case, we can just see the shape of the Jacobian peak in different ET/pT cuts.  If this is the key reason lead to the discrepancy, there should be significant changes on the "Jacobian Peak" for different ET/pT shape. The following plots are for different luminosity ranges for both W+ and W-.

1. Full sample
1.1 W+, (Different color stand for different ET/pT cuts.)
1.1.1 Data:

1.1.2 Embedding:

1.2 Full sample: W-
1.2.1 Data:

2. Low luminosity: 
2.1 W+

2.2 Low Luminosity W-:

3. High Luminosity:
3.1 W+
3.1.1 Data:

3.2 High Luminosity: W-

 For above plots, we can't see clear indication that the mis-matching between ET and pT lead to the Peak shape change. 
? can we pass this possible reason with these checking ?
