Comparison of stellar mass for optically (top panel) and UV-selected (bottom panel) green valley galaxies using colour (C1 (g − r) and C2 (NUV − r), blue dashed histograms), SFR-M_* (C3 and C4, red solid histograms, sSFR (C5 and C6, green dotted histograms), and colour with Gaussian fit (C7 (g − r) and C8 (NUV − r), black dot-dashed histograms)) criteria. The vertical dashed lines in both panels represent the median values of each criterion applied.
