Abstract

In order to compute stellar orbits in spiral galaxies the gravitational potential and its pattern speed must be known. Observationally, these parameters are difficult to determine, in particular for strongly barred galaxies. We will briefly review different methods and illustrate in more detail the case where the problem has been approached by numerical gasdynamical simulations.
