1  Fit uses coupled channel model accounting for ${{\mathit D}^{0}}{{\mathit D}^{*+}}$ threshold.
2  The fit uses a relativistic ${\mathit P}{\mathrm -wave}$ Breit-Wigner function without taking into account the ${{\mathit D}^{0}}{{\mathit D}^{*+}}$ threshold. Parameters are shown to be biased in AAIJ 2022Z. The significance for ${\mathit m}_{{{\mathit T}_{{{c c}}}^{+}}}−({\mathit m}_{{{\mathit D}^{*+}}}$ + ${\mathit m}_{{{\mathit D}^{0}}}$) $<$ 0 is 4.3 $\sigma $.
