Using the Mathematica package, we find exact analytical expressions for the so-called de-projected de Vaucouleurs and Sérsic laws as well as for related spatial (3D) quantities – such the mass, gravitational potential, the total energy and the central velocity dispersion – generally involved in astronomical calculations expressed in terms of the Meijer G functions.
