The $\ppiMinus$ experimental correlation function is shown in black as a function of the pair relative momentum $k^*$ for several intervals of the pair \mtText: (a) $[0.54, 0.75)\text{ GeV}/c^2$, (b) $[0.75, 0.95)\text{ GeV}/c^2$, (c) $[0.95, 1.2)\text{ GeV}/c^2$, (d) $[1.2, 1.5)\text{ GeV}/c^2$, (e) $[1.5, 2.0)\text{ GeV}/c^2$, and (f) $[2.0, 2.5)\text{ GeV}/c^2$. The lines and boxes show the statistical and systematic uncertainties of the experimental data, respectively. The fit results according to Eq. \eqref{Eq. ProtonAntiPion Exp Fit} are depicted by the red bands. Contributions of correlated background, final-state interaction, and $\Delta^{0}(1232)$ are shown as the green, blue, and yellow bands, respectively. The width of the bands represents the uncertainty from the fitting procedure.
