Fraction of input galaxies detected in eRASSl (red) and eRASS:4 (blue) as a function of X-ray flux (top left), redshift (top right), stellar mass (bottom left) and r-band magnitude (bottom right). Different symbols, between eRASS1 and eRASS:4, are slightly shifted horizontally for illustration purposes. In the top left panel, the red dotted line shows the eRASS1 sensitivity curve (Seppi et al. 2022). In all subplots, upper subpanels show the number of galaxies in each bin. 1σ (3σ) binomial confidence intervals (Cameron 2011) are shown in black (gray).
