ALMA Band 4 cutouts and spectra for all sources in G073. The upper panels show 3″  ×  3″cutouts, with continuum images in the background highlighted by orange contours starting at 2σ and increasing in steps of 3σ. For sources with line detections, moment-0 contours (red) are overlaid following the same steps. The lower panels show the continuum-subtracted LSB and USB spectra, with the best-fitting Gaussian functions plotted over the raw data and the shaded regions indicating the integration range used to measure the line strengths.
