Main line parameters derived for high-excitation lines and 29SiO absorption.
| Molecular line | Total flux mJy × km s−1 | Peak brightness mJy beam−1 × km s−1 | Δ(RA) mas | Δ(Dec) mas |
|---|---|---|---|---|
| H2O ν2 = 2 3(2,1)–4(1,4) | 370 ± 15 | 174 ± 7 | 11 ± 3 | 3 ± 3 |
| Si17O ν = 1 J = 8–7 | 100 ± 6 | 53 ± 4 | 10 ± 3 | 2 ± 3 |
| CO ν = 1 J = 3−2 | 310 ± 7 | 132 ± 5 | 11 ± 3 | 3 ± 3 |
| 29SiO ν = 0 J = 8–7 (abs.) | –53 ± 4 | –48 ± 4 | 9 ± 4 | 0 ± 4 |
| SO 3Σν = 1 9(8)–8(7) | 307 ± 8 | 130 ± 5 | 14 ± 3 | 5 ± 3 |
Notes. We always give the RA and Dec offsets with respect to the total continuum centroid: 23:43:49.4962, –15:17:04.72.
