Physical properties, as derived by CIGALE, for the seven different merging classes of (U)LIRGs. From top to the bottom, M_dust, M_star, sSFR, T_dust, and L_PDR are plotted as a function of the merging class. Each circle (following the colour coding of Fig. 6) corresponds to an individual system. Black diamonds stand for the median values per galaxy type, while the associated 16th and 84th percentile ranges are indicated with error bars. Distributions of class ‘s’, ‘M1’, and ‘M3’ systems, with the corresponding colour, are also presented as side plots.
