1  AAIJ 2020J combines mass measurements $3621.53$ $\pm0.24$ $\pm0.29$ MeV from ${{\mathit \Xi}_{{cc}}^{++}}$ $\rightarrow$ ${{\mathit \Lambda}_{{c}}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{+}}$ and $3621.95$ $\pm0.60$ $\pm0.49$ MeV from ${{\mathit \Xi}_{{cc}}^{++}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{+}}{{\mathit \pi}^{+}}$ . Supersedes AAIJ 2018BA and AAIJ 2017BC.
2  The third error in AAIJ 2018BA value is from the uncertainty of the ${{\mathit \Xi}_{{c}}^{+}}$ mass.
3  The third error in AAIJ 2017BC value is from the uncertainty of the ${{\mathit \Lambda}_{{c}}^{+}}$ mass. The width of the signal is $6.6$ $\pm0.8$ MeV, consistent with the experimental resolution.
