Invariant-mass distributions for $\rm D^0$ candidates in selected $p_{\rm T}$ intervals for the centrality class 0$-$10% and 30$-$50%. Fitted values for the $\rm D^0$ meson mass $\mu$, width $\sigma$, and raw yield $S$ are also given, the fraction of $\rm D^0$ candidates in the measured raw yield is reported with its statistical and systematic uncertainties. Top row: non-prompt $\rm D^0$ mesons with $1<\pt<2$ $\gev/c$ in the 0$-$10% centrality class, before (left) and after (right) subtraction of the background fit function. Bottom row: non-prompt $\rm D^0$ mesons with $1<\pt<2$ $\gev/c$ (left) and $7<\pt<8$ $\gev/c$ (right) in the 30$-$50% centrality class.
