  \caption{Model parameters for the central star of SMP~61. 
 {\em Stellar core parameters}: 
 Stellar luminosity~$L_\star$, 
 temperature~$T_\star$ and radius~$R_\star$. 
 {\em Wind parameters}: 
 mass-loss rate $\dot{M}$, 
 terminal wind velocity~$v_\infty$, 
 clumping factor $D$, and the corresponding transformed radius~$R_{\rm t}$. 
 {\em Atmospheric abundances}: 
 Mass fractions~$X_{\rm He}$, $X_{\rm C}$, and~$X_{\rm O}$ are determined by the model fit 
 (Fig.~\ref{fig:spec}) whereas~$X_{\rm Si}$ is set to a~standard LMC~value.  
 For~$X_{\rm Fe}$ and~$X_{\rm N}$ upper limits are given. 
 The hydrogen mass fraction~$X_{\rm H}$ could not be determined in the present analysis. 
 {\em Interstellar parameters}: 
 Distance modulus~$M - m$ for the~LMC, 
 color excess due to interstellar extinction~$E_{B-V}$, 
 and~Ly~$\alpha$ hydrogen column density~$n_{\rm H}$.}  \label{tab:parameters}
