Notes. The reason some colour indices are missing is that the we do not have light curves and light ratios for all systems in all colors. For (B − V) we have calculated the colour indices by finding solutions where all components are constrained to the main sequence. This is done to be able to put all systems on the same CMD (Fig. 1).
