Map of the excitation processes in the field of view of MUSE. Top: RGB map with star formation in green, AGN or shocks in blue, composite in red. The contours show the UV emission from GALEX (black; left) and the Hα-[N ii] emission from MUSE (white; right). Middle: separation of the AGN or shocks excitation (left), and the SF+composite excitation (right). Bottom: separation of the AGN or shocks excitation (left), and the SF+composite excitation (right) for the velocity range of the CO emission (− 256.8 <v< − 194.5 km s^-1; relative to Centaurus A). The APEX beams are represented by the circles.
