 The DJR 1 %$\rightarrow$% 0, 2 %$\rightarrow$% 1, 3 %$\rightarrow$%2 and 4 %$\rightarrow$% 3 are given for each production. The contribution of each multiplicity is given. The smoothness of the transition region indicates how much the choice of xqcut and Qcut in the matching procedure is valid. <br /> <img width="450" alt="Q2_33_50_0bis.jpg" src="%ATTACHURLPATH%/Q2_33_50_0bis.jpg" height="293" />
 
-This plot is out from a production of ttbar+0,1,2 jets with mt = 350 GeV. The curves for the zero and one jets multiplicities appear at the left handside of the cutoff, which means that the scale at which the showered partons are grouped into one jets (this is the 2 to 1 plot) is smaller than 50 GeV. This is normal as the maximal distance in the phase-space to characterize a jet is the cutoff. Therefore only the two partons events ,i.e. the events with showered partons more far to each other than the cutoss, can be above the cutoff. Beside the detailed description for each production, the comparison of DJR is done between productions. The goal is to check the invariance of the global shape with respect to the choice of the cutoff but also to be able to compare difference coming from other parameters related to the generation. In the figure taken from two production of tt+0,1,2,3 jets done with a slight difference of factorization scale in the ME generation, the comparison permit to understand the effect of this change over the rates. <br /> <img width="450" alt="Q3_comparison_30_30.jpg" src="%ATTACHURLPATH%/Q3_comparison_30_30.jpg" height="293" />

 4.2 Kinematics For each production, the PT (X), %$\Delta\phi$%(X) (if X is two particles: tt, ZZ, WW, WZ, etc...), %$\eta$%(X), m(X), the PT of one particle composing X and also his rapidity are showed.
 
-For each PT cut choosen by the user, the rapidity of each jet is also given
