Left panel: integrated CO(1−0) map of NGC 6240 (based on natural weighting, and in logarithmic scale in Jy). Stars indicate the positions of the two AGN. The large cross indicate the phase tracking center. The contours are 3σ, 5σ, 10σ, 20σ, 30σ, 40σ and 50σ. Labels indicate the positions where we extracted the spectra shown in Fig. 2. Right panel: continuum-subtracted CO line spectrum, integrated in a circular region of radius 3′′ centered on the peak of CO emission. The spectral channels are 26 km s^-1 wide.
