Left: L_IR versus L₈ for the whole 5MUSES sample. Black circles correspond to purely star-forming and composite sources, while red triangles correspond to AGN. The solid grey line depicts the median and 68% dispersion of composite and star-forming galaxies. Right: L_IR/L₈ versus EW of 6.2 μm. The horizontal lines enclose the values of L_IR/L₈ within the 68% dispersion from the median. The orange lines depict the best-fit linear regression and its scatter in the EW_6.2 ≥ 0.4  μm regime. Purple squares correspond to sources with f_AGN > 0.5.
