$\langle T_{\rm AA} \rangle$-scaled yield of muons from W$^-$ and W$^+$ decays in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV for muons with $\pt^\mu > 10$ GeV/$c$ and $2.5 < y^\mu_{\rm cms} < 4.0$. The measured production is compared with HG-PYTHIA  calculations of the $R_{\rm AA}$ of hard scatterings scaled with the centrality-averaged production in 0--90\% centrality, indicated as dashed lines. The horizontal bars correspond to the width of the centrality intervals, the vertical bars and boxes indicate the statistical and systematic uncertainties, respectively.
