From a simultaneous fit to all obtained correlation functions, real and imaginary components of the scattering lengths, as well as the effective ranges, were extracted for combined $\\rm p\\overline{\\Lambda}$ and $\\rm \\overline{p}\\Lambda$ pairs and, for the first time, for $\\Lambda\\overline{\\Lambda}$ pairs.
