Satellite fraction f_s as a functionof threshold luminosity, with L^* as a reference point (left panel) and as a function of threshold stellar mass, with M^* as a reference point (right panel). Results obtained in this work at z ~ 3 (filled symbols) are compared with similar measurements from lower redshift ranges. In the left panel the dashed line indicates the satellite fraction as measured at z ~ 0 by Zehavi et al. (2011), while in the right panel results found by Skibba et al. (2015) at z ~ 0.5 are shown with open triangles.
