SFR and Compton y relation for star-forming (upper panel), transitioning (middle panel), and passive galaxies (lower panel) in the zoom-in region of SSC. The colour scale indicates the number of pixels for each combination of SFR and y. The dots and bars are the median and 68% distribution, respectively. Vertical black lines correspond to the same tSZ outer (solid orange, y_outer = 2.2 × 10⁻⁶) and inner (dashed black, y_inner = 1.1 × 10⁻⁵) contours in Fig. 4.
