Yield of beauty-hadron decay electrons in 0--10\% central Pb--Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02 {\rm TeV}$ for the TPC--TOF and TPC--EMCal analyses compared with the pp reference scaled by $\left< t_>$, obtained from the measured cross section for \pt $< 8$ \GeVc, which is extrapolated up to $p_\mathrm{T}= 26 \GeVc$ using FONLL. The ratio of the yields using TPC--TOF and TPC--EMCal analyses in the overlapping interval of $3 < \pt < 8 \GeVc$ in Pb--Pb collisions is shown in the bottom panel. < /t_>
