Sample results for the $R$ and $\lambda$ parameters extracted in the present analysis from K$^0_{\rm S}$K$^{\rm \pm}$ femtoscopy using the Achasov1 parameters. The left column compares K$^0_{\rm S}$K$^{\rm +}$and K$^0_{\rm S}$K$^{\rm -}$ results from the quadratic baseline fit method, and the right columncompares results averaged over K$^0_{\rm S}$K$^{\rm +}$and K$^0_{\rm S}$K$^{\rm -}$ for the quadratic baseline fits and the linear baseline fits Statistical uncertainties are plotted for all results.
