F. ; Richstone, D. O. Abstract Two surveys of axisymmetric scale-free models of E6 elliptical galaxies are created and compared. The models are constructed using Schwarzschild's linear programming method. One survey has the same geometry as an earlier set of models with constant mass-to-light ratio, the other has M/L increasing with r. As expected from the hydrostatic equation, the M/L inversely proportional to r models have smaller velocity moments than the constant M/L models. However, this effect is less severe in the high angular momentum models. The shape and tilt of the omega-z velocity ellipsoids are almost identical in two models with the same constraints and objectives but different radial falloff.
