Distribution of the central CO 2−1 emission in high resolution (left) and intensity distribution of the gas surrounding the AGN, which is associated only with the second velocity component in the CO 2−1 spectrum (right). Crosses and numbers from 1 to 11 mark the positions of the GMAs. GMA 5 is located at the peak position of the 1.4 GHz radio continuum (Beswick et al. 2005). The beam (0.43′′ × 0.38′′) is shown in the lower left corner of the panels. The contours are at every 1.0 Jy km s^-1 starting at 1.0 Jy km s^-1; blue dotted contours are the negative counterparts of the lowest positive contour.
