We describe a method for parameterizing two-integral distribution functions,based on triangular tesselations of the integral plane. We apply the method tothe axisymmetric isotropic rotator model for the Galactic bulge of Kent~(1992),and compare the results with observations of proper motions in Baade's Window,and with radial velocity surveys. In spite of mounting evidence from surfacephotometry and from study of the gas kinematics that the Galactic bulge is notaxisymmetric, the stellar kinematics in Baade's Window are very similar tothose of an isotropic oblate rotator. Another field at large radius does notfit this model, though. In any case, the edge-on kinematics of a hot stellarpopulation are a poor handle on the existence or otherwise of a bar.Comment: 19 pages, 700 kb uu-encoded compressed postscript file, CfA preprin
