Dust continuum maps, best-fit Gaussian modeling, and residuals for the lensed z6.1-6.2 (arc, top rows) and z6.3 (bottom rows) images. The side of each cutout is 10". The rest-frame wavelengths of each map are labeled. Blue contours are at 2,  3,  5, and 10σ (rms). The images are color-scaled within ±5 times the rms per pixel in each band. The beam is shown in the bottom-right corner of the cutouts of the residuals.
