Notes. The intensities were derived by adding all the channels in the velocity ranges −360 < v < −260 km s−1 (blue) and −260 < v < −160 km s−1 (red), relative to Centaurus A. For non-detections, an upper limit at 3σ has been derived assuming a linewidth of 50 km s−1, that is the typical linewidth of the 12CO(1-0) line. The last column gives the ratio of the line with the 12CO(1-0).
