Our SED models (solid black curves) for the observations (black points) of four sample LIRGs, including IRAS 17578−0400 (top left), MCG+08-11-002 (top right), CGCG 049−057 (bottom left), and IRAS 16516−0948 (bottom right). The model components include a spheroidal (dot dashed orange) or a disc (dot dashed green), starburst contribution (dashed red), and an AGN (dotted blue). We note that the starburst component of IRAS 17578−0400 dominates the total emission and is overlapped by the combined model curve, due to the small contribution of the other components.
