1AAIJ 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.

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.
