Table 1.
Calibrators used during the two ALMA observing runs.
| Field | RA, Dec (J2000) | Time (min) |
|---|---|---|
| J2258–2758 | 22:58:05.96288, −27.58.21.2567 | 5.31 |
| J2357–5311 | 23:57:53.26608, −53.11.13.6893 | 2.79 |
| J2328–4035 | 23:28:19.26485, −40.35.09.8463 | 6.38 |
| J2248–3235 | 22:48:38.68574, −32.35.52.1881 | 3.02 |
Notes. First column: J2258 = bandpass calibrator; J2357 = flux calibrator; J2328 = phase calibrator; J2248 = check source reference target (pointing accuracy and point source nature). In run 2 the source J2258–2758 was used as a bandpass, flux, and pointing calibrator, and J2328–4035 was used as a phase calibrator (see: https://almascience.eso.org/sc/ for details about the calibrators.). Last column: time on target during the first run. These data were taken from the output of the ALMA data reduction procedure as provided by the ALMA arc node.
