Abstract : The sedimentation level of blue straggler stars (BSS) has been shown to be a great tool to investigate the dynamical states of globular clusters. In this work, we estimate the area enclosed between the cumulative radial distributions of BSS and a reference population, A+, for 12 open clusters as a measure of the sedimentation of BSS in these open clusters. We study the correlation of A+ with other dynamical and structural parameters of OCs. From this analysis, we comprehend that independent of the nature of a stellar system, A+ always represents the dynamical state of the cluster. However, only OCs containing reasonable numbers of BSS, allow an estimation of A+ without a large error associated with this estimation.
