Invariant-mass distributions of $\mathrm{D}^{*+}$ candidates with $4<p_\mathrm{T}<6$ GeV$/c$ and $0.0<|\cos{\vartheta^*}|<0.2$ (left panel) and $15<p_\mathrm{T}<30$ GeV$/c$ and $0.8<|\cos{\vartheta^*}|<1.0$ (right panel) for $0.3<|y|<0.8$ in 30-50% Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV. The background distribution is modelled with a threshold function, while the signal with a Gaussian function.
