Figure 14. The r PCAC (left panel) and r PPD (center panel) ratios (de(cid:12)ned in eqs. (4.1) and (4.2)) at the physical point in the continuum limit. These are obtained using a 2P (dotted, blue), z 4+3 (solid, green) or a z 4+4 (dashed, red) (cid:12)t ansatz. In the case of r PPD , we also show results of the corresponding (cid:12)ts that are constrained to be consistent with PCAC in the continuum limit (right panel), cf. table 3.
