Notes. The orbital phase was computed from the centroid JD following Fekel et al. (2000). The first errors on the flux density measurements only represent the 1σ statistical errors due to noise. The second errors are the additional systematic uncertainty of the ALMA absolute flux calibration of 2.5% in bands 1 – 5 and 5% in bands 6 – 8 (away from strong atmospheric absorption as in our case) (Cortes et al. 2024).
