Our purpose here is to continue the study of the ergodic decomposition for actions defined by amenable groups, started in [R. Zaharopol, Colloq. Math. 165 (2021)]. We consider the set Γ^(w)_αcpie defined in the above-mentioned paper, and we prove that it is Borel measurable and of maximal probability.
