Bar fraction for the Coma (red), Virgo (blue), and SMACS0723 (violet) clusters as a function of both the absolute r-band magnitude (left panel) and the stellar mass (right panel). The bar fractions have been computed using only disc galaxies (ORDINARY) within a clustercentric radius of 0.3 × r₂₀₀ (see text for details). The number of galaxies in each bin is shown at the top of each panel coloured accordingly. As explained in the text, bins are represented either every 0.5 mag or 0.25 dex, but the fraction (and therefore the number of galaxies) is averaged over bins of 1 mag and 0.5 dex for the magnitudes and masses, respectively.
