Figure 9. Violation of PCAC (left panel) and PPD (right panel) displayed for various ensembles along the trajectory with constant average quark mass (green lines in (cid:12)gure 2) at (cid:12) = 3 : 55. The plots show the ratios de(cid:12)ned in eqs. (4.1) and (4.2). The (cid:12)lled circles are obtained taking into account the pion pole enhanced excited states directly in the (cid:12)t functions, while the crosses were obtained using a traditional (cid:12)t ansatz (with the same excited state energies in the two- and three- point
