Comparison between the SF mode of the primary and the secondary component. The coloured symbols show the morphology of the primary (unfilled symbols) and secondary (filled symbols) components as shown in the legend. The solid and dashed magenta lines show the MS, and the black line shows the one-to-one relation. The SF mode distributions of the primary and secondary component are shown in the top and right panel, respectively. The SF mode distributions are coloured by morphology as shown in the legend.
