"Auxiliary Figure 5(c)" of "Search for pair- and single-production of vector-like quarks in final states with at least one $Z$ boson decaying into a pair of electrons or muons in $pp$ collision data collected with the ATLAS detector at $\sqrt{s} = 13$ TeV"

Observed upper limits at 95$%$ CL on $\sigma(pp\rightarrow B\bar B)$ for the combination of the pair-production channels for all combinations of BRs for $B\rightarrow Zb$, $B\rightarrow Hb$, $B\rightarrow Wt$ adding up to unity for a $B$-quark mass of 950 GeV.
