Systematic (top) and random (bottom) relative errors in the reconstruction of in Test D, in the 3 redshift bins considered in this study (x-axis). We only show results for , but trends with redshift are similar for other values. These values correspond, respectively, to the thick and thin lines in the bottom panels of Fig. 5, for the given value. The value of the scatter is obtained by averaging the lower and upper values of the scatter (the two thin lines in Fig. 5). Solid line is for R₅ and dotted line for R₈. Different colours correspond to the different methods (blue: WF; green: LNP; orange: ZADE; red: cloning).
