$\pt$-differential production cross section of prompt $\rm D^+_s$ mesons in $\pPb$ minimum-bias collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV compared with a pp rescaled reference af the same center-of-mass $A \mathrm{d} \sigma / \mathrm{d} \pt$, where $A$ is the atomic mass number. Statistical uncertainties (bars) and systematic uncertainties from data analysis (empty boxes) and from feed-down subtraction (full boxes) are shown. Horizontal error bars reflect the bin widths, symbols are located at the center of the bin.
