\caption{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
