We use the following values for our parametersg A/gV=−1.18, λ-2.12,g 2/4π=14.5,m=1192 MeV,m Ν=1115 MeV,m *=1383 MeV,m N = 939 MeV,m π=139 MeV.

We may observe that in the works of ref. (2) the 33 resonance gives an overestimate for the constantg A/gV. In our case too this feature is displayed, since we overestimate the constantD A: (D A)theor>(D A)exp.
