ALMA continuum bands of the arc (top rows, 7.5″ side) and the z6.3 image (bottom rows, 5″ side). The rest-frame wavelength of each map is labeled. The ALMA images are color-scaled within ±5 times the rms per pixel in each band. Solid (positive) and dashed (negative) blue contours are at ±3,  5,  7, and 9σ. The solid red line and shaded area indicate the aperture adopted to extract the photometry. The beam size is shown in the bottom-right corner of each cutout. The bottom-right panel of each series shows the JWST/NIRCam image at 4.5 μm. In the latter, the point spread function has a full width at half maximum of $0\stackrel{″}{.}16$ and the blue contours mark the continuum at 158 μm (C5+C2). The blue bar shows a 10 kpc scale.
