Absence of energy equipartition. The galaxies are divided in bins according to their stellar mass. This plot shows the variation of σ_los(M_⋆), which is the velocity dispersion of the cluster members inside the nth bin normalized to the global velocity dispersion, with galactic mass. The errors were evaluated as , where N is the number of elements inside the nth bin. In green is the trend expected in the presence of complete energy equipartition ().
