The sedimentation level of blue straggler stars (BSS) has been shown to be a great tool investigate the dynamical states globular clusters (GCs). area enclosed between cumulative radial distributions BSS and reference population up half-mass radius clusters, $A^+_{\mathrm{rh}}$, is known measure in GCs. In this work, we calculate $A^+_{\mathrm{rh}}$ for 11 open (OCs) using combined list main-se...
