Left panels: velocity dispersion versus line shift with respect to the systemic velocity of the H I and CO, respectively, in logarithmic scale. Colours identify different regions in the plot. Pixels consistent with the model of rotation are shown in blue, while pixels in the kinematical region of rotation are shown in light blue. The purple ellipses are the same as in the left panel of Fig. 9. Right panels: distribution of the H I and CO, respectively. Colours correspond to the plot in the left panel. Radio jets are shown in grey. The H I and CO different loci, in particular R6 and the rotating regions, are distributed similarly to the ionised gas regions, but on a larger scale.
