$R^{2}_{\rm long}$ vs. $m_{\mathrm{T}}$ for kaons and pions The solid lines show the fit using Eq. ($\ref{eq:tau_YS}$)for pions and kaons to extract the emission times ($\tau$); the dashed and dotted linesshow the fit using Eq. ($\ref{eq:tau_stand}$) with $T_{\rm kin}$ = 0.144 GeV and $T_{\rm kin}$ = 0.120 GeV, respectively. For pions at small $m_{\mathrm{T}}$, the dashed and dotted line coincide
