Notes. (a) By assuming $T_{\rm d}=30$ K (see Sect. 4.3 and Table 4), $M_{\rm cont}=39~M_{\odot}$, $N_{870}({\rm H_2})=0.75\pm0.05\times10^{22}$ cm-2, $N_{870}/N_{8}=1.0\pm0.1$, and $\langle n({\rm H_2}) \rangle=0.2\times10^4$ cm-3.
(b) By assuming $T_{\rm d}=30$K, $M_{\rm cont}=20~M_{\odot}$, $N_{870}({\rm H_2})=0.49\pm0.05\times10^{22}$cm-2, $N_{870}/N_{8}=0.9\pm0.1$, and $\langle n({\rm H_2}) \rangle=0.3\times10^4$ cm-3.
(c) By assuming $T_{\rm d}=30$K, $M_{\rm cont}=66~M_{\odot}$, $N_{870}({\rm H_2})=0.82\pm0.05\times10^{22}$cm-2, $N_{870}/N_{8}=5.9\pm0.4$, and $\langle n({\rm H_2}) \rangle=0.3\times10^4$ cm-3.
(d) No error given because it is greater than the actual value.
(e) By assuming $T_{\rm d}=30$K, $M_{\rm cont}=80~M_{\odot}$, $N_{870}({\rm H_2})=1.08\pm0.05\times10^{22}$cm-2, $N_{870}/N_{8}=3.0\pm2.0$, and $\langle n({\rm H_2}) \rangle=0.4\times10^4$ cm-3.
