description We discuss a procedure for fitting a set of dimension-6 effective field theory param- eters using simplified template cross section measurements. The steps are to determine equations relating the parameters to the cross sections, choose the fit parameters and external constraints, and perform the fit. In this example the equations are calculated using the HEL model in the Madgraph generator, which is a partial implementation of the SILH basis at leading order in perturbation theory.
