    2222The  [https://feynrules.irmp.ucl.ac.be/attachment/wiki/SMEFTatNLO/definitions.pdf definitions.pdf] document specifies the operators definitions, normalisations and coefficient names in the UFO model
    2323=== Usage notes ===
    24 Because of the mixture of LO/NLO compatible operators included in the model, restriction cards must be used to access the SMEFT interactions. Default loading of the model

    4146We recommend specifying the full {{{QCD}}}, {{{QED}}} and {{{NP}}} orders for process generation.

    4853Generates the NLO QCD top pair production process including the QCD-induced SM and the SMEFT contributions.

     55==== Excluding operators ====
     56
     57We recommend avoiding setting values of Wilson coefficients to 0 when computing at NLO using MadGraph5_aMC@NLO.
     58
     59Operators should either be removed explicitly with restriction cards or set to a very small non-zero value, e.g., 1e-10
