Abstract
We present a set of Stackel potentials which can be used for dynamical modelling. Each of them has a halo-disk structure and is the superpos ition of two Stackel potentials. The main criterion was the extent of the flat part of its rotation curve. To that end, we examine the shape and relative mass contribution of both disk and halo. Each rotation c urve we retained as being flat, seems to be a 'maximum-disk' rotation curve. As an application, we search for potentials which can be used a s a potential for the Milky Way. The selection of the parameters is ca rried out on the observational constraints in the solar neighbourhood. The potentials which are retained reveal information about the shape and mass of the disk and dark halo of the Galaxy, and the relative con tribution of each component, and can be used for dynamical modeling of tracer populations requiring a third integral of motion.
