Estimates of F_TIR/F_7.7 as a function of stellar mass for the IR-bright sample, using Herschel constraints. Scatter points are color-coded by the fraction of dust mass in PAHs. Median relations are shown for the full 3D-Herschel sample (red) and for the IR-bright sample inferred without FIR data with a fixed template (purple; equivalent to the 24 μm–to–70 μm color of the log average of the D. A. Dale & G. Helou 2002 templates). The dashed line marks the mass–F_TIR/F_7.7 relation from I. Shivaei et al. (2024).
