ALMA images of ASXDF1100.053.1 and 231.1. First column: Cleaned ALMA 1100 μm continuum images taken in ALMA Cycles 1 and 2. Synthesized beams of the combined data are 0.″46 × 0.″35 (PA, 69°) and 0.″57 × 0.″48 (PA, 82°) for ASXDF1100.053.1 and 231.1, respectively. Contours are shown at 5, 10, 15, 20, and 25σ. The flux density unit is mJy beam⁻¹. The rms noise level is shown at the bottom in each panel. Second column: Clean component maps of the combined ALMA images are shown in the middle panel. The clean component maps were obtained by cleaning down to 1σ. Third column: Synthesized beams for the combined ALMA images. Fourth column: Residual maps after subtracting the clean components convolved with the synthesized beams. The pixel scale is 0.″05 in all images.
