Notes.
The observational phase center for the observations detailed in the table was (J2000) RA 08:30:51.156, Dec +01:32:24.35. These are the same coordinates as the observations used in Yang et al. (2019). Spectral window and observed lines therein.
Date of ALMA observation.
Central frequency of the spectral window containing the specific line.
Channel width of the calibrated and imaged data for the specific line.
Synthesized beam of the spectral window using natural weighting.
Per-channel RMS of the spectral window.
The combined H2O+ lines are the hyperfine structure H2O+(202 − 111)5/2 − 3/2 lines at 160.28 GHz.
