*The numbers in parentheses represent the errors in units of last significant digits.

^†The spectral line of C¹⁸O is used for evaluation of the column density of CO, where the ¹⁶O/¹⁸O ratio is assumed to be 560 (Wilson & Rood 1994).

^‡The spectral line of ¹³C¹⁸O is used for evaluation of the column density of ¹³CO, where the ¹⁶O/¹⁸O ratio is assumed to be 560 (Wilson & Rood 1994).

^§The spectral lines of the ³⁴S species are used for evaluation of the column density, where the ³²S/³⁴S ratio is assumed to be 22 (Chin et al. 1996).

‖Two optically-thin hyperfine components are used for evaluation of the column density.

^|$\#$|The spectral lines of the ¹³C species are used for evaluation of the column density, where the ¹²C/¹³C ratio is assumed to be 60 (Lucas & Liszt 1998).
