Neutral gas velocity field (km s⁻¹), velocity dispersion (km s⁻¹), and flux intensity (mJy) maps for the single kinematic component used to model NaD. The black lines are as in Fig. B.11. Specifically, the black solid line indicates the major axis of the stellar rotation (Table 4). The dashed lines indicate the orientation of the radio jet (Table 1). The contours indicate the region at high velocity dispersion (Sect. 5.4 for details).
