A representation of the CO observations made with the NRAO 12 m telescope (the 55﹩\arcsec﹩ FWHM beam is indicated). The vertical scale of the CO spectra is the antenna temperature ﹩T^{*}_{R}﹩ in millikelvins, and the horizontal axis is the redshift in units of km s−1. The total CO luminosity in NGC 6670 is ~70% of the sum of the two beam measurements.
