CO detections and spectral profiles of the nine new detected sources. Left panels show the moment zero maps with the ±3, ±4, and ±5σ level contours, while the right panels display the extracted CO spectra. The grey shaded regions around each spectrum represent the ±1σ RMS noise level estimate from the individual data cubes, and the blue shaded region indicates the velocity range used to create the moment maps. The final row, right figure, presents the rest-frame stacked spectrum of non-detections with ±1σ and ±2σ levels. A summary of the integrated CO fluxes and associated uncertainties for all detected sources is provided in Table A.1
