Scientific paper

Using ESO 2.2m/WFI optical data in two bands, we computed the galaxy luminosity functions of five groups of galaxies, selecting group members with the color-magnitude relation. By integrating the luminosity function, we calculated the stellar masses of our groups. We then calculated the X-ray gas mass and the total group mass from the density and temperature profiles obtained from XMM-Newton X-ray data. This enabled us to derive the baryon fraction in our groups and to compare it with those from other studies of groups and clusters.
