Evolution of the mean IRX with stellar mass in four redshift bins based on the measurements from the COSMOS2020 FIR-detected sources (empty circles), FIR stacked sources (filled diamonds), and the HSC-CLAUDS sample with or without the IRX stacking correction (solid and dashed lines, respectively). In the bottom right panel, we show the behaviors for the COSMOS2020 FIR stacking in the four redshift bins.
