CO(1–0) spectra of NGC 6240 extracted from the D configuration data in circular regions of 2′′ radii encompassing the extended, blueshifted emission eastward (solid black histogram) and southwestward of the nuclei (red dashed histogram). The extraction regions are centered on offsets of (7.6′′, 1.3′′) and (–6.4′′, –6.8′′) from the phase-tracking center.
