Maps of H₂ S(5) at 6.909 μm (top) and H₂ S(1) at 17.03 μm (bottom) constructed as explained in Sect. 2.2. Panels show the intensity and contours in a square root scale in arbitrary units (left), the mean-velocity field in units of km s⁻¹ (middle), and the velocity dispersion map σ (corrected for instrumental resolution) in units of km s⁻¹ (right). The velocity contours are in a linear scale (solid lines positive values and dashed lines negative values). The star symbol marks the peak of the continuum adjacent to the line, that is, the AGN position. The 0,0 point on the axes refers to the center of the corresponding sub-channel array. North is up and east to the left.
