In all four main panels, top left subpanel: distribution of morphological parameters vs. luminosity, color-coded with redshift. The black line shows the best-fitting line (see Sect. 4.2). In the bottom left subpanel, we show the distribution of morphological parameters vs. redshift, color-coded with luminosity. The black line again shows the best-fitting line. The gray shaded area represent the scatter around the best-fit line. The red data point shows (when a direct comparison can be made) the result value obtained by Lovisari et al. (2017), which can be directly compared with the blue data point, which shows our results when we restricted the luminosity and redshift range to the same range as in Lovisari et al. (2017). The orange data point represents the average morphological parameter values obtained in luminosity or redshift quintiles. We show parameters corrected for redshift and luminosity evolution against luminosity (in the top right subpanel) and redshift (in the bottom right subpanel).
