These parameters are extracted by analyzing and fitting the mass distributions of the pairs in the final \\(\\bar{K}^0\\pi^+\\eta\\) state. To ensure the reliability of the results, we apply resampling techniques to evaluate statistical uncertainties and improve the precision of the scattering parameters.
