Notes.

(†)

HPBW (half power beam width) for observations with the IRAM 30 m telescope and synthetic beam for the ALMA SV observations.

(††)

Range of frequencies considered in the analysis. Nevertheless, between 7−50 GHz and 80−115.5 GHz only three lines of HSO (39.532, 81.364, and 81.368 GHz) with large intensities are expected (a-type transitions, Sij ≥ 1, and Eup between 0 and 200 K).
