Popis:	For a source proper, source connected regular symplectic groupoid acting locally free and effectively in a Hamiltonian way with proper moment map having connected fibres there is an associated Duistermaat-Heckman measure on the quotient orbifold. We show that this measure is polynomial with respect to the natural affine measure. Comment: 11 pages. Provisional version, comments welcome!
