Abstract

We take a sample of 24 elliptical and lenticular galaxies previously analysed by the SAURON project using three integral dynamical models created with Schwarzschild method, and re-analyse them using the made-to-measure (M2M) method of dynamical modelling. We obtain good agreement between the two methods in determining the dynamical mass-to-light ratios (M/L values) for the galaxies with over 80 percent of ratios differing by
