(General comments about the panels as in Fig. A.1.) IRAS F18093-5744 (S) (IC 4689): this galaxy has a spiral morphology in the NICMOS/HST image, without clear evidence of strong interaction with the other galaxies of the system. The kinematic center seems to be coincident with the VIMOS continuum peak: the velocity field shows a mostly regular pattern, typical of a rotation-dominated disk-like object. Its velocity dispersion map shows a centrally peaked structure. It also shows regions in the northern part with relatively large velocity dispersion (~100 km s^-1). A small area (~0.6 kpc²) at the center shows the presence of a broad component, blueshifted by ~85 km s^-1. The scale is 0.353 kpc/′′.
