Table 2: Number of interacting galaxies observed (N) and detected ($N_{\rm d}$) according to the different ISM tracers. The column labeled "All'' represents the number of galaxies present in each morphological type bin. The type 11 is assigned here to galaxies whose structure is not attributed to a specific morphological type in LEDA.
