     283 === input
    284284 1. The model use for this validation is the EWDIM6 (See: http://arxiv.org/abs/arXiv:1205.4231). 10k events where generated with the standard model (cross-section:  0.8008 ± 0.0026 pb)
    285285 2. The reweight_card was:
    … …  
    318318The same scan was done for the three first coupling (CWWW, CW, CB)
    319319
    320 This is the result:
     320=== result:
    321321 1. For CWWW
    322 ||   Coupling value ($TeV^{-2}$)   ||    Reweight cross-section (pb)   ||      MadEvent cross-section (pb)   ||   Status   ||
    323 ||    0.01                ||  0.800810008029             ||  0.7973 ± 0.0023  || OK ||
    324 ||    0.1                 ||  0.800903791291             ||  0.799 ± 0.0026   || OK ||

    326 ||    10                  ||  0.85200014698              ||  0.8584 ± 0.00092 || OK ||
    327 ||    100                 ||  5.0238030968               ||  6.09 ± 0.0082    || '''FAIL''' ||
    328 ||    100                 ||  5.04763                    ||  6.09 ± 0.0082    || '''FAIL'''  (make with a sample of 100k events) ||
    329 
    330   1. The last entry fails since the expected distribution for such value of the coupling is too different from the distribution of the Standard Model. Such discrepancy are expected in this case. One hint is that the cross-section is an order of magnitude higher than the original one (Looking at the distribution confirm this).
    331   2. The inversed reweight (i.e. starting from the CWW=100 sample of events and reweight to find back the SM) is working properly. It returned: 0.803341120226

    334  2. For CW

    342   Same comment as for the previous coupling.

    347 ||    0.1                 ||  0.800782626532             ||  0.7985 ± 0.0024    || OK ||
    348 ||    1                   ||  0.800626859275             ||  0.7981 +- 0.002365  || OK ||
    349 ||    10                  ||  0.799127987884             ||  0.7971 ± 0.0024 || OK ||
    350 ||    100                 ||  0.790019392142             ||  0.7852 ± 0.0026    || OK ||

    352   This operator has less impact on the cross-section/distributions, and therefore even a large value of the coupling is still working fine.
