Figure Caption

Invariant-mass distribution with background subtracted of $\rm{D}^{0}$ candidates and charge conjugates in the $1 < p_{\rm{T}} < 2$ GeV/c interval in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV for the 0-10% centrality class. The blue curve shows the total fit function (signal + background).
