SFE as a function of gas fraction (f_gas) for PP, NP, and PN galaxies in the low-mass (upper panel) and high-mass (lower panel) bins. All parameters are expressed relatively to those of NN galaxies at a given M_★. The coloured map represents the normalised SFR, while green borders around the data points highlight galaxies that increased their stellar mass by more than 25% within 2.5 Gyr (τ₂₅ < 2.5 Gyr). The percentages of each galaxy type within each quadrant are included.
