Upper panel: CO(1–0)  maps from the compact array data, in velocity bins of 20 MHz each (velocity labels are rounded off), showing the detection of blueshifted CO, including structures extended on scales of 10–15′′. The positions of the two AGN nuclei are shown by crosses. The synthesized beam is shown in only the first panel, for clarity. Each contour is 5σ (limited to 20σ). Lower panel: maps from merged data of the D and A configurations in the same velocity channels. The synthesized beams are shown in the bottom-left corners.
