Notes. ^(a) Peak number of channels with a continuum-subtracted flux density above 6σ in setups S1 and S2, excluding channels covering CO 2–1, ¹³CO 2–1, C¹⁸ O 2–1, SiO 5–4, SO 5₆ –4₅, OCS 18–17, and OCS 19–18. This value corresponds to the peak of the contour map shown in Fig. 2. The total bandwidth is 6.4 GHz. ^(b) Number of spectral lines with a peak flux density above 6σ in setups S1 and S2 toward the continuum peak, excluding the transitions listed above. ^(c) Average number of channels with a flux density higher than 6σ per detected line with a peak flux density above the same threshold. ^(d) Spectral density of lines detected above 6σ toward the continuum peak.
