Notes. (1)Field of view (FOV) corresponding to the combined primary beam of the 1.3 mm and 3 mm mosaics, down to 15% of the peak sensitivity. (2)Angular resolution resulting from a tclean process with the Briggs robust parameter robust=0. (3)Noise level measured in the bsens and cleanest 12 m array images at 1.3 mm and 3 mm. (4)The maximum recoverable scale of the 12 m array, often called the largest angular scale (LAS), is estimated for each 1.3 m and 3 mm images as the 10th percentile of the baseline lengths of 12 m array data (see Figs. 5–7 of Ginsburg et al. 2022).
