We look for evidence of mass segregation in these clusters by tracing the variation in the value of $\\alpha$ in different regions of the cluster as a function of the parameter $\\tau = t_{age}/t_{relax}$ (where $t_{age}$ is the age of the cluster and $t_{relax}$ is the relaxation time of the cluster), Galactocentric distance, age and size of the cluster.
