14. We are able to fit this (large) number of parameters because we use a Bayesian fit in which each parameter is given a prior value. The prior values are incorporated into the fit's χ 2 function in such a way that each counts as an additional piece of input data. As a result, the number of degrees of freedom in the fit always equals the number of pieces of original Monte Carlo data, however many parameters there are. Adding terms to the fit function that are not needed can only increase the final errors. We include such terms to make sure that our systematic errors are not underestimated. Generally, we add terms at least until the fit results and χ 2 stop changing. For more details see: G.P. Lepage, Nucl. Phys. B, Proc. Suppl.
