(General comments about the panels as in Fig. A.1.) IRAS F18093-5744: the whole system consists of three galaxies in interaction, which have been observed separately. The nuclear separations between the northern (IC 4687) and the central galaxy (IC 4686) and between the central and the southern galaxy (IC 4689) are ~10 kpc and ~20 kpc, respectively. The HST (F110W) image shows a spiral-like morphology for IC 4687, with several knots and concentrations in the nuclear region. IC 4687 shows a velocity field dominated by rotation, with the kinematic center well defined and coincident with the nucleus (continuum maximum). On the other hand, the velocity dispersion map shows an almost centrally peaked map, with higher values in the outer parts of the galaxy, corresponding to ionized regions (see Monreal-Ibero et al. 2010). The scale is 0.353 kpc/′′.
