\begin{table}%t6 \caption{Summary of results from dust continuum emission modeling (above mid-line) and from molecular line emission modeling (below mid-line). The relative uncertainties are at the 3$\sigma$ level, and they\protect correspond to the rms noise propagated through the modeling process.} \label{tab:summary} %\begin{center} \par \begin{tabular}{l|cc} \hline\hline ~ & MM1 & MM2 \\ \hline \par $L$ & 14~000~\lsol & 2~700~\lsol \\ $T_*$ & 22~500~K & 16~600~K \\ $M_{\rm gas}$ & $660\pm 130$~\msol & $460 \pm 100$~\msol \\ $r_{\rm ext}$ & 27~300~AU & 21~600~AU \\ $n_0$ & $2.8~(0.6)$~$\times$~10$^{9}$~cm$^{-3}$ & $1.1~(0.2)$~$\times$~10$^{10}$~cm$^{-3}$ \\ $\left$ & $8.0~(2.0)$~$\times$~10$^{5}$~cm$^{-3}$ & $1.1~(0.2)$~$\times$~10$^{6}$~cm$^{-3}$ \\ $p$ & --1.2~$^a$ & --1.3~$^a$ \\ $T_{\rm ext}$ & $25.4~(0.5)$~K & 19.2~(0.4)~K \\ $\left$ & $27.3~(0.2)$~K & 19.4~(0.2)~K \\ $\alpha$ & $-0.588~(0.011)$ & --0.614~(0.012) \\ $\beta$ & $3.95~(0.03)$ & $3.85~(0.04)$ \\ $r_{\rm in}$ & 21~(2)~AU & 12~(1)~AU \\ \hline \par $\varv_{\rm T}$ & $1.0~(0.1)$~\kms & $1.7~(0.1)$~\kms \\ $X$(CS) & $1.0~(0.3)$~$\times$~10$^{-9}$ & $5.4~(1.5)$~$\times$~10$^{-10}$ \\ $X$(C$^{34}$S) & $5.1~(1.4)$~$\times$~10$^{-11}$ & $2.7~(0.8)$~$\times$~10$^{-11}$\\ $X$(N$_2$H$^+$) & 3.5~(0.8)~$\times$~10$^{-10}$ & 6.3~(1.4)~$\times$~10$^{-10}$\\ $X$(HCO$^+$) & 2.3~(0.7)~$\times$~10$^{-9}$ & 5.1~(1.6)~$\times$~10$^{-9}$\\ $X$(H$^{13}$CO$^+$) & 3.4~(1.1)~$\times$~10$^{-11}$ & 7.6~(2.4)~$\times$~10$^{-11}$\\ $X$(p-H$_2$CO) & 1.5~(0.4)~$\times$~10$^{-10}$ & 2.6~(0.7)--4.8(1.3)~$\times$~10$^{-10}$\\ $X$(o-H$_2$CO) & 1.3~(0.4)~$\times$~10$^{-10}$ & 2.0~(0.6)~$\times$~10$^{-10}$\\ {}[para/ortho] & $\simeq$1.2 & $\simeq$1.3--2.4 \\ \hline \multicolumn{3}{c}{} \\ \end{tabular}\\ $^a$ Values from continuum map analysis by \citet{beuther2002a}. %\end{center} \par \end{table}
