Notes. Spatial offsets along the right ascension (RA) and declination (Dec) directions: they are defined as the difference between the position of the Hα flux intensity peak and that of the VIMOS continuum (rest frame 6390−6490 Å) intensity peak (i.e., x_Hα − x_cont, y_Hα − y_cont). The coordinates (x_i, y_i) of the peaks in the maps have been derived as the flux-weighted mean position when considering 3   ×   3 spaxels around the maximum intensity value. A typical error of 0.34′′ is estimated. For double systems having both galaxies in the VIMOS FoV, the position of the peak refers to the one used as reference to center the images. Column (4): notes with the following code: (a) the peak of the VIMOS continuum image is considered the center of the images since the Hα peak corresponds to an extranuclear knot of star formation and does not properly define the center of the galaxy. (b) For this galaxy, it was not possible to identify the VIMOS continuum peak due to the S/N.
