We present here axisymmetric two and three integral models of the S0 galaxy NGC 3115. The light and mass models are based on an application of the Multi-Gaussian Expansion (MGE) method on V band images of NGC 3115. The resulting model fits the photometry from the central HST pixel (0.045 arcsec) up to a radius of ~ 500 arcsec (combining a wide field image kindly provided by Cecilia Scorza, an HRCAM/CFHT image, and the WFPC2/HST image). The deprojection is analytical if each component corresponds to a 3D Gaussian. Here, the model is assumed axisymmetric. The analytical expression of the luminosity density serves as the input for all the dynamical models.
