 1 Uses ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{-}}$ and ${{\mathit \Xi}_{{c}}^{+}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays. Reports the value of $6044.3$ $\pm1.2$ $\pm1.1$ ${}^{+0.19}_{-0.22}$ MeV where the last uncertainty is due to the mass of ${{\mathit \Xi}_{{c}}^{+}}$. We have combined the two systematic uncertainties in quadrature.
 2 Reconstructed in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Omega}_{{c}}^{0}}{{\mathit \pi}^{-}}$ , ${{\mathit \Omega}_{{c}}^{0}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays. Reference ${{\mathit \Xi}_{{b}}^{-}}$ mass $5797.72$ $\pm0.6$ MeV from AAIJ 2014B.
 3 Uses ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ and ${{\mathit \Omega}_{{c}}^{0}}{{\mathit \pi}^{-}}$ decays, with the first evidence for ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Omega}_{{c}}^{0}}{{\mathit \pi}^{-}}$ at 3.3 $\sigma$ significance.
 4 Measured in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ with $19$ $\pm5$ events.
 5 Observed in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ decays with $16$ ${}^{+6}_{-4}$ candidates, a significance of 5.5 sigma from a combined mass-lifetime fit.
 6 Observed in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ decays with $17.8$ $\pm4.9$ $\pm0.8$ candidates, a significance of 5.4 sigma.
