Velocity (left panel) and velocity dispersion (right panel) maps of the stellar component derived from cube2 with the pPXF fitting. White contours tracing continuum are overplotted as a spatial reference (for the southern nucleus we used 19% of the 1.2 μm continuum maximum and for the northern nucleus 6% of the 2.3 μm continuum maximum). Crosses and the ellipse indicate respectively the nuclei and the high-velocity molecular hydrogen blob positions (see Section 4.3.1). From the velocity map, we can distinguish the two stellar rotating disks in the proximity of the two nuclei.
