We present a set of Stackel potential which can be used for dynamical modeling. Each of them has a halo-disk structure and is the superposition 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 curve we retained as being flat, seems to be a 'maximum-disk' rotation curve. As an application, we search for potentials which can be used as a potential for the Milky Way. The selection of the parameters is carried out on the observations constraints in the solar neighborhood. The potentials which are retained reveal information about the shape and mass of the disk and dark halo of the Galaxy, and the relative contribution of each component, and can be used for dynamical modeling of tracer populations requiring a third integral of motion.
