Notes. Note: (1) Epoch of observation, (2) ALMA project code, (3) central frequency in GHz, (4) and (5) observation date in yyyy-mm-dd and MJD unit respectively. (6) Beam size in unit of arcseconds along major and minor axes, (7) physical beam size in unit of parsecs along major and minor axes, (8) peak flux density with original beam size in mJy beam⁻¹, (9) peak flux density with $7 . 31^{''} \times 4 . 96^{''}$ $7.31^{\prime \prime } \times 4.96^{\prime \prime }$ beam size in mJy beam⁻¹, (10) signal-to-noise ratio of the detection. We used 10% uncertainties for flux density in all epochs.
