Table 6. Results obtained from the !2P and the ! z 4+3 (cid:12)t including the statistical error () s and estimates of the systematic uncertainties due to quark mass extrapolation () m , due to the continuum extrapolation () a , and due to additional excited state e(cid:11)ects () ex . The systematics are speci(cid:12)c to the particular (cid:12)ts and do not re(cid:13)ect di(cid:11)erences between (cid:12)tans(cid:127)atze. Since both (cid:12)ts satisfy PCAC in the continuum, G A (0) = m ‘ G P (0) holds m
