(General comments about the panels as in Fig. A.1.) IRAS F18093-5744 (C): the Hα emission from the source is highly concentrated in the nuclear region. Ionized gas emission is also observed extending towards the northwest of the nuclear region, probably as part of a tidal tail linking this galaxy with IC 4687. The VIMOS continuum emission is strongly contaminated by a star located in the northwest part with respect to the galaxy. The northern/western part of the velocity field is dominated by the kinematics of the tidal tail, which shows redshifted velocities and very low velocity dispersion: the blue part of the velocity field is not well defined, even excluding the region south of the nucleus. Due to the presence of the tidal tail, the interpretation of the broad component in the innermost region is uncertain (i.e., it may correspond to the main systemic component because it is the narrow one associated with the tidal tail). The scale is 0.353 kpc/′′.
