(General comments about the panels as in Fig. A.1.) IRAS F14544-4255 (IC 4518): this system is formed by two galaxies with a nuclear separation ~12 kpc, which were observed separately using two VIMOS pointings. The present panels correspond to the eastern source. This galaxy has a faint tail extended towards the northwest, as seen in the DSS image (see Paper III). The Hα image reveals a very strong knot of star formation towards the southeast of the nucleus (~2.5 kpc): for this reason, the VIMOS continuum peak is used to identify the center (0,0) of the images. The velocity field is rather regular, although some deviations of pure rotation pattern are seen towards the west, probably due to the projection of star-forming knots with peculiar velocity. Its velocity dispersion map has a relatively constant value of σ_mean ~ 60 km s^-1 in almost the whole FoV. The broad component found in a few spectra has velocity dispersion values similar to those of the narrow component. The spatial scale is of 0.32 kpc/′′.
