Distribution of stellar mass versus rest-frame colour (u_JAVA − r_SDSS) obtained from miniJPAS sources with r_SDSS ≤ 22.5 and P_G ≥ 0.5 at different redshift bins. Top: diagram of the (u_JAVA − r_SDSS) colour after correcting for dust effects or intrinsic colour. Bottom: diagrams without correcting the rest-frame (u_JAVA − r_SDSS) colour for extinction and normalised histograms of P_Q values for each redshift bin (see insets). The dashed black line illustrates the limiting relation for selecting quiescent galaxies and AUTO photometry at the central redshift of each bin (i.e. z = 0.15, 0.4, and 0.6; see Eq. (1)). Dots are colour coded according to the quiescent and star-forming classification (redder and bluer colours, respectively) or quiescent probability (P_Q).
