Fit results of the $\rho$ distribution for muons with $6 < \pt < 7~\GeV$ in \pp collisions (left) and in \PbPb collisions with 20--30\% centrality (right). The ratios of the data to fit results are shown in the lower panels. The prompt-muon background contributions are very small in the fitted muon kinematic region. The grey bands in the lower panels indicate the statistical and systematic uncertainties combined in quadrature.

(Top) \dcaT templates for different background contributions, and data \dcaT distributions before (solid points) and after (open points) background subtraction for muons with $6 < \pt < 7~\GeV$ in \pp collisions (left) and in \PbPb collisions with 20--30\% centrality (right). (Bottom) Fit results of the background-subtracted \dcaT distribution for muons with $6 < \pt < 7~\GeV$ in \pp collisions (left) and in \PbPb collisions with 20--30\% centrality (right). The vertical dashed lines indicate the \dcaT range, $|\dcaT| < 0.5~\mathrm{mm}$, used in the fit procedure. Data to fitted result ratios are shown in the bottom panels. The grey bands indicate the statistical and systematic uncertainties combined in quadrature.

Differential cross section of charm (left) and bottom (right) muons as a function of muon \pt, plotted at the centres of the \pt intervals, in \pp collisions at $\sqrt{s} = 5.02~\TeV$ in comparison with FONLL calculations. Data results and FONLL calculations for bottom muons both include the $b\rightarrow c\rightarrow \mu$ contribution. Statistical uncertainties in the data are shown as vertical lines and systematic uncertainties in the data and calculation are shown as boxes.

Differential per-event invariant yields of muons from charm hadron decays (left) and bottom hadron decays (right) as a function of \pt, plotted at the centres of the \pt intervals, for different centrality intervals in \PbPb collisions at $\sqn = 5.02~\TeV$. For each centrality interval from peripheral to central, an additional scaling factor of $2$ is applied to the plotted points for visual clarity. Statistical uncertainties are shown as vertical lines and systematic uncertainties as boxes.

Nuclear modification factor, \RAA, for muons from charm hadron decays (top panels) and bottom hadron decays (bottom panels) as a function of \pt for five different centrality intervals. The centrality intervals are separated for clarity into the left (0--10\%, 20--30\%, 40--60\%) and right (10--20\%, 30--40\%) panels. Statistical uncertainties are shown as vertical lines and uncorrelated systematic uncertainties as boxes around the points. Correlated fractional systematic uncertainties, including \TAA and \pp luminosity uncertainties, are isolated as coloured boxes around unity for different centrality intervals.
