"Aux Figure 17" of "A detailed map of Higgs boson interactions by the ATLAS experiment ten years after the discovery"

Observed correlation matrix from the fit of $\kappa_{Z}$, $\kappa_{W}$, $\kappa_{b}$, $\kappa_{t}$, $\kappa_{\tau}$ and $\kappa_{\mu}$ coupling modifiers with $\kappa_{c}$ = $\kappa_{t}$ in the fit. All fitted parameters are assumed to be positive. No contributions from non-SM invisible and undetected Higgs boson decays are allowed, i.e. $B_{inv.}=B_{u.}=0$.
