ALMA observations of XLSSC 122. From top to bottom, we show the raw (dirty) continuum images of the 12 m-array mosaic, ACA mosaic, and the jointly imaged Band 3 observations. The latter image (bottom panel) is tapered with a uv-taper of 20 kλ. Black contours in each panel are drawn at [−4.5, −3.5, −2.5, −1.5, 1.5, 2.5, 3.5]-σ except for the top panel, which excluded the ±1.5σ contours. We find a central noise RMS of σ = 0.051, 0.014, 0.022 mJy beam⁻¹, respectively. The dashed circles in all panels indicate r_500, c centered on the BCG. The green contours in the bottom panel indicate the ACT-y map contours and are drawn at [2.5, 3.5, 4.5, 5.5] times the local noise level. The beams of the ACA, ALMA, and jointly imaged ACA+ALMA observations are indicated in the lower-left corner of each panel. We clearly see that the ACT and ALMA+ACA observations align spatially.
