Notes. Columns (3)–(8) of this table are as follows: (3) LSR velocity; (4) FWHM linewidth; (5) peak line intensity; (6) integrated intensity; (7) peak optical thickness (see Sect. 4.3/Appendix A.3).
Integrated intensity is derived by integrating over the velocity range indicated in square brackets. Note that the high-velocity blueshifted wing in the 13CO spectrum towards SMM 2 was excluded from the integrated intensity. For DCN(3 − 2), the percentage 92.6% in brackets indicates the contribution of hf component’s intensity lying within the detected line.
