Integrated CO(4 − 3) and CO(2 − 1) spectra, extracted from the cubes at the common spatial resolution. The CO(2 − 1) flux is multiplied by a factor of four to facilitate comparison with the CO(2 − 1) flux. Upper left: emission integrated over the whole disk, that is within an ellipse with a 12′′ major axis, 4′′ minor axis, and –65°position angle. Upper right and bottom: emission integrated within a beam (i.e., within a radius of 0.28′′) from the nucleus, and from the north and south radio lobes.
