| DCO+ | 3−2 | 216.1126 | 20.7 | ALMA Band 6 | 2″ | Murillo et al. (2018b) |

| p−H2O | 31,3−20,2 | 183.3101 | 204.7 | ALMA Band 5 | 0.25″ | |
| o−H2O | 11,0−10,1 | 556.9360 | 61.0 | Herschel HIFI | 0.25″ (b) | Kristensen et al. (2012) |
| HCO+ | 3−2 | 267.5576 | 25.7 | ALMA Band 6 | 0.25″ | Hsieh et al. (2019b) |
Notes. (a)Previous work that reports observations of the transitions used for the line emission radiative transfer models. (b)The spatial resolution in Kristensen et al. (2012) for o-H2O is 39″. A much smaller beam of 0.25″ is used in order to compare with HCO+.
