The d$N$/d$y$ (left) and $\langle \pt \rangle$ (right) as a function of system size for ${\rm K}^{*\pm}$ (closed marker) and ${\rm K}^{*0}$ (open markers)  in Pb$-$Pb collisions at $\snn$ = 5.02 TeV and $\snn$ = 2.76 TeV . Comparison with predictions of MUSIC hydrodynamic model with and without the hadronic phase afterburner (SMASH) are presented by solid and dashed lines, respectively. Statistical (systematic) uncertainties are shown by bars (boxes).
