Examples of invariant-mass distributions of the $\Xi^{-}$ (\ref{fig:XiMinus_TripleGaussian}), $\overline{\Xi}^{+}$ (\ref{fig:XiPlus_TripleGaussian}), $\Omega^{-}$ (\ref{fig:OmegaMinus_TripleGaussian}) and $\overline{\Omega}^{+}$ (\ref{fig:OmegaPlus_TripleGaussian}). The measured mass $\mu$ and mass resolution $\sigma$ from the fit, with their associated statistical uncertainties, are displayed.
