Comparison of peak intensities of lines observed by both Herschel (3.5 m) and JCMT (15 m).

| CO 7–6 | 88 ± 44 | 22 ± 2 | 4 ± 2 | ≳10 |
| HCN 9–8 | 9 ± 4.5 | 0.32 ± 0.03 | 28 |

| HCN (ν2 = 1) 9–8 | 4 ± 2 | <0.2 | >10 | <3 |
Notes. JCMT intensities are taken from Boonman et al. (2001), Herschel intensities are from this work. The HCN (ν2 = 1) 9–8 upper limit for Herschel is derived from the ~0.1 K 1-σ noise level near 797.3 GHz in our spectrum. The inferred size of the emission region, θs, is calculated using Eq. (1).
