Top panel: VIMOS continuum (6390−6490) Å image within the rest-frame wavelength range. When available, the HST continuum image is also shown. Middle panel: the Hα flux intensity, velocity field, v (km s^-1), and velocity dispersion, σ (km s^-1), for the narrow component. Bottom panel: similar maps for the broad component. The flux intensity maps are represented in logarithmic scale (applying a factor of − 13) in units of erg s^-1 cm^-2 for the Hα flux maps and erg s^-1 cm^-2 Å^-1 for the continuum map. The center (0,0) is identified with the Hα flux intensity peak and the iso-contours of the Hα flux map are overplotted. North is at the top and East to the left in all the panels. IRAS F01159-4443 (ESO 244-G012): this is an interacting pair with a nuclear separation ~8.4 kpc, where the northern galaxy shows the brightest nuclear emission in both the Hα and continuum maps. The two galaxies show regular velocity fields in the narrow component. The scale is 0.462 kpc/′′.
