Flux and kinematics maps of four neon lines. The flux (left), velocity (centre), and velocity dispersion (right) of the [Ne II] 12.8 μm, [Ne III] 15.6 μm, [Ne V] 24.3 μm, and [Ne VI] 7.7 μm transitions are shown to provide a context about the circumnuclear region of NGC 5728 (north is up, east is left). As the ionisation potential increases from 22 eV to 126 eV (top to bottom), what the line emission traces changes from star formation in the ring to the outflow. The direction of the major kinematic axis and the central dispersion change correspondingly. Interestingly, the outflow kinematics reveal anomalous velocities and unusually high dispersion along the minor axis, which is especially noticeable in the [Ne III] line.
