In \cite{humi}, we studied a Hamiltonian action for a generalized Calabi-Yau manifold and showed that the Duistermaat-Heckman theorem holds. The purpose of this note is to show that the density function of the Duistermaa-Heckman measure is a piecewise polynomial. We also prove that the localization formula holds.4pages, addendum to "Reduction for generalized Calabi-Yau structures"Differential GeometrySymplectic Geometry37J15, 14J32text
