Left panels: SDSS cutout images (g r i composite, field of view = 60″ × 60″, scale = 0.5″/pixel, north is up and west is right) of ALLSMOG galaxies, showing the 27′′ APEX beam at 230 GHz. Right panels: APEX CO(2-1) baseline-subtracted spectra, rebinned in bins of δν = 50 km s^-1 (2MASXJ1437+0500, 2MASXJ1048+1201, SDSSJ1110+1345, PGC 012214, PGC 003530, PGC 073268, PGC 1452135, PGC 3127469), or 25 km s^-1 (PGC 051743, SDSSJ0944+0400), depending on the width and S/N of the line. The corresponding Hi 21 cm spectra are also shown for comparison, after having been renormalised for visualisation purposes (Hi references are given in Table C.5).
