$\mathbf{\textbf{K}^{0}_{\textbf{S}}}-\mathbf{\textbf{K}^{0}_{\textbf{S}}}$ femtoscopy in Pb$-$Pb collisions at $\mathbf{\sqrt{\textit{s}_{\rm NN}} = 5.02}$ TeV at the LHC

Correlation functions with the respective fits in four \kt ranges for \PbPb collisions at \fivenn in the 10-30\% centrality range. Statistical uncertainties are shown as the black bars and systematic uncertainties, described in Sec. \ref{sec:Systematics}, are shown as boxes. The linear baseline contribution is shown in blue and the Lednický-Lyuboshitz model from Eq. \ref{eq:Led} is shown in green. The total fit, shown in red, corresponds to Eq. \ref{eq:Cfit} and is obtained by fitting the product of the baseline and the Lednický-Lyuboshitz model to the data. The shaded band around the fit represents the 95\% confidence interval, reflecting statistical uncertainty on the fit parameters.
